This work introduces a revised peridynamic integration paradigm that enables high-fidelity simulations using substantially fewer integration points while maintaining accuracy. The key observation is that conventional peridynamic volume integration can be reformulated as two separable components, radial and angular, allowing independent numerical treatment of each. Building on this decoupling, we propose a peridynamic integration framework that couples Gauss– quadrature in the radial direction with Lebedev spherical quadrature for angular integration (PD-GL). This reformulation yields three main advances: (i) systematic reduction of integration points via structured projection algorithms, (ii) removal of repeated neighbor-search overhead through spatial hashing, and (iii) retention of high accuracy even for small horizons <jats:inline-formula> <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\" overflow=\"scroll\"> <mml:mi>δ</mml:mi> <mml:mo>=</mml:mo> <mml:mn>2</mml:mn> <mml:mspace width=\".1em\"/> <mml:mrow> <mml:mi mathvariant=\"normal\">Δ</mml:mi> </mml:mrow> <mml:mi>x</mml:mi> </mml:math> </jats:inline-formula> , where conventional peridynamics typically deteriorates.

This paper presents a novel methodology for simulating concrete cracking at the macroscale while considering mesoscale characteristics and overcoming the difficulties of generating computational specimens. To this end, a tensile damage model incorporating high aspect ratio interface elements via mesh fragmentation is employed to capture nonlinear behavior. The Rule of Mixture is utilized to derive effective properties. A notched square plate under uniaxial tensile loading is simulated, and the average result from five mesoscale realizations is compared with a single macroscale result, considering varying aggregate fractions and shapes. A three-point bending test and an L-shaped panel test are also performed to verify the effectiveness of the strategy under different fracture modes, and the results are compared with experimental and computational references. The findings demonstrate the efficacy of the approach in capturing mesoscale characteristics through macroscale analysis, encouraging further application to more complex analyses, such as thermomechanical or three-dimensional problems, which involve more computationally demanding aggregate arrangements in the mortar matrix.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"14 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147635909","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By introducing bond force distance attenuation and progressive damage evolution mechanisms, a novel damage constitutive model was developed, and a dynamic 3D bond failure criterion was proposed to consistently couple the energy condition, strength constraint, and strain rate effect. Furthermore, the stretch corresponding to the peak bond force, traditionally solely determined by the macroscale strength, was extended to be jointly governed by the macroscale strength and bond microscale parameters. This modification characterizes the variability of the bond stretches corresponding to the peak bond forces in heterogeneous materials, thereby improving the model's capability to describe material heterogeneity and differences in local failure. 3D benchmark examples were conducted to compare various attenuation functions, quantitatively verifying that the exponential attenuation form yields the minimum overall error index. Based on three validation cases, the influences of internal cross-fissure angle and depth on impact stress response, 3D crack propagation path and energy distribution were systematically analyzed. Results indicate that under impact loading, increased cross-fissure depth decreases peak stress and energy utilization efficiency; at a constant depth, peak stress increases first and then decreases with the rising intersection angle. Crack propagation presents symmetry and eventually forms a funnel-shaped 3D crack, with the minimum damage degree inside the funnel.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"5 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147635745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multiphase mesoscopic modeling method is proposed to capture and accurately represent moisture-driven swelling effects. The synergistic evolution of porosity, permeability, and damage, along with its influence on the mechanical response under cyclic wetting and drying, is examined.

Drawing on multiscale design principles inspired by biological tissues, the concept integrates nanoscale crack deflection, microscale fiber reconfiguration, and macroscale adaptive chemistry to suppress damage evolution entirely. The model is implemented within the continuum mechanics framework, incorporating nonlinear elasticity, evolving internal variables, and bioinspired architecture. Two numerical examples are presented to illustrate the predictive capacity and physical insight of the formulation: (1) the dynamic response of aortic tissue under a quasi-static tensile load, and (2) the quasi-static compression behavior of swine brain tissue. Both simulations demonstrate the feasibility of achieving undamageable-like responses in soft biological materials through controlled hierarchical structuring. In the first example, the aorta is modeled as an undamageable hyperelastic composite, where collagen fiber realignment and reversible matrix reconfiguration prevent microstructural fatigue. The resulting stress–strain response exhibits full recovery over thousands of cycles, reproducing the self-preserving elasticity observed experimentally in arterial walls. In the second example, undamageable behavior is examined in swine brain tissue subjected to large deformations. The proposed constitutive model captures the tissue's remarkable resilience to permanent damage through energy dissipation and internal reorganization of microstructural networks. These results confirm that the undamageable material framework not only describes an idealized limit of damage-free performance but also provides a powerful tool for interpreting and replicating the extraordinary endurance of biological tissues.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"21 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study proposes an interpretable hybrid stacking framework, RF–DEGWO–LSTM, for uncertainty-aware dam deformation forecasting. Random forest (RF) acts as a nonlinear feature-based learner and provides embedded feature importance; differential evolution grey wolf optimizer (DEGWO) is used to tune key long short-term memory (LSTM) hyperparameters; and a meta-learner fuses RF and DEGWO–LSTM outputs into a unified predictor that explicitly captures time-varying, non-stationary relationships between hydrostatic, thermal and aging factors and displacement. The framework is validated using long-term monitoring data from two dams (a concrete gravity dam and a run-of-the-river dam). Comparative experiments against RF, plain LSTM, recurrent neural networks (RNNs), eXtreme Gradient Boosting (XGBoost) and DEGWO–LSTM show that the RF–DEGWO–LSTM model consistently achieves the highest R <jats:sup>2</jats:sup> and the lowest error metrics. In the most challenging scenario, RF–DEGWO–LSTM improves test-set R <jats:sup>2</jats:sup> by approximately 5–10% and reduces root mean square error by about 15–20% relative to the best single-model baseline. Residual analyses indicate reduced bias and variance, while interpretability based on RF feature importance and LSTM attention confirms the dominant roles of hydrostatic and seasonal components, with aging effects being secondary. Accurate forecasting of deformation is critical for early identification of damage evolution and integrity loss in large civil infrastructure. The proposed framework thus offers an accurate, robust and interpretable tool for data-driven dam deformation forecasting and early-warning-oriented structural health management.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"36 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147586733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the traditional grouting technology mainly plays a bonding role, it has a limited effect on the reinforcement of the surrounding rock fractures. In order to improve the density of the slurry and enhance its reinforcement effect, an expansion agent can be mixed in the grouting material. Based on the Mohr–Coulomb criterion, an equivalent model for slurry reinforcement of fissured rock masses was established in this study, with the expressions for rock mass strength under various reinforcement techniques derived, and the strengthening mechanism of slurry reinforcement on fissured rock masses elucidated. Through indoor uniaxial compression tests and numerical simulation methods, this study investigates the crack initiation and propagation characteristics of rock masses with different fracture angles, and analyzes the reinforcement mechanisms and effects of ordinary slurries and expansion slurries on fractured rock masses. The study indicates that expansion slurry provides superior reinforcement compared to ordinary slurry, with the increase in expansion stress significantly improving the grouting reinforcement effect. Grouting improves the strength of fractured rock masses, though it does not fully restore their original strength. Post-grouting, the fissured rock mass exhibits a change in damage mode, with initial crack propagation occurring along the slurry–rock interface. Subsequently, the cracks propagate obliquely toward the prefabricated fissures, culminating in the overall splitting failure of the rock mass with the slurry-rock interface as the core. Through the expansion agent grouting reinforcement method, the transportation roadway of Jintong Coal Mine was reinforced, and the surrounding rock was effectively controlled, which proved the superiority of expansion agent grouting reinforcement.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"18 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147536461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results show that the conventional framework is often difficult to accurately describe the whole creep process, while the energy dissipation theory model can clarify the distinguishing features of each stage by analyzing the change of energy. In the transient creep stage, the elastic energy contained in the rock structure is gradually released and accompanied by partial energy dissipation. The experimental values are in good agreement with the anticipated values, particularly during the stage of accelerated creep. That is, damage mechanics model for creep processes established within this investigation can characterize the nonlinear characteristics of its initial, constant, and rapid creep phases.

An integrated approach combining experimental investigations with crystal plasticity finite element analysis elucidates the relationship between microstructure evolution and macroscopic mechanical properties. Experimental results show that yield strength decreases by 48.5% (from 1422 to 733 MPa) and ultimate tensile strength by 45.2% (from 1596 to 875 MPa) as temperature increased from 25°C to 600°C. Detailed metallographic observations of fracture surfaces and deformed regions reveal a progressive transition from quasi-cleavage fracture to ductile fracture as the temperature rises. Building upon these experimental insights, a temperature-dependent crystal plasticity finite element model is developed, incorporating both dislocation density evolution and strain-based damage accumulation. This model provides an accurate representation of the deformation behavior of AISI H13 steel across the temperature range studied. Through a comparison of experimental and simulated results, the validity and robustness of the model are confirmed. The model further unravels the underlying failure mechanisms, that at room temperature, tensile failure in AISI H13 steel is primarily driven by stress concentrations resulting from the multiplication and entanglement of dislocations. However, at elevated temperatures, the failure mechanism shifts toward grain softening and subsequent plastic deformation, which is facilitated by the annihilation of dislocations.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"15 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147507858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
