The heat conduction equation in the present situation has been established taking into account the Moore–Gibson–Thompson generalized heat equation within a slipping interval on assimilating the memory-dependent derivative. The rod is assumed to be fixed at both ends and thermally insulated. The governing equations have been solved by the Laplace transform mechanism and in order to arrive at the solutions in real space–time domain, inversion of the Laplace transform has been performed using the method of Zakian. The computational results have been obtained for various values of damage parameter to reveal significant effect of various parameters such as hyperbolic two-temperature parameter, classical two-temperature parameter, various kernel function, nonlocal parameter and the time delay also. Various comparative studies have been performed to analyze the impact of damage on each physical fields.

The first part includes a detailed assessment of the three-dimensional (3D) stress status and the result shows that the shear stresses substantially influence the deltoid matrix failure and skin-stiffener debonding. In the second part, a high-fidelity 3D damage model, with a modified damage initiation failure criterion based on Hashin and Puck is implemented via ABAQUS/EXPLICIT VUMAT user-subroutine. The intralaminar damage model considers 3D stress states and continuous stiffness degradation theory while for interlaminar failure, the cohesive-zone method based on bi-linear traction separation law is used. The mechanical response, as well as the intralaminar and interlaminar damage predicted by the model, shows a good correlation with the experimental findings. The results model shows a maximum error of 8% in the case of load versus time and a maximum error of 2.5% in the case of energy absorbed with the experimental results. Overall, the impact behavior of integrated composite structures can be effectively predicted using the recommended method.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"114 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145188783","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 novelty of the approach lies in the integration of three distinct damage models—the Voigt parallel model, the Reuss serial model, and the generalized self-consistent model—into a force-based framework. These models are employed to capture stiffness degradation in RAC beams under isotropic and homogeneous conditions, addressing the need for more realistic damage representation in sustainable concrete structures. The Kerr-type foundation model accounts for interaction between the beam and its underlying foundation, while the Euler–Bernoulli beam theory governs the beam's deformation behavior under small displacements. The governing equations are formulated using the virtual force principle. Through a series of numerical simulations, the study investigates how damage mechanisms and system parameters influence the bending response of the RAC beam–foundation system. The results demonstrate that both the type of damage model and foundation characteristics significantly affect the structural stiffness, leading to either softening or stiffening responses.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"23 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141190","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}

Macroscopic and microscopic tests were conducted to explore the thermal damage evolution of concrete under microwave irradiation in this paper. Uniaxial compressive strength test was employed to investigate the impact of microwave irradiation on concrete macroscopic mechanical. Concurrently, scanning electron microscopy test, X-Ray diffraction analysis, and computed tomography scan test were utilized to investigate microstructure evolution and chemical content variation. The results show that the response of basalt aggregate to microwaves was stronger than that of the mortar, resulting in thermal gradient stress between them, leading to interface debonding and concrete damage. Within the temperature range of 100°C–300°C, the water liberated by AFt (Ettringite) hydrolysis evaporated in conjunction with the free water within the concrete, leading to the increment of porosity and rapid growth of cracks. Within 300°C–500°C, CH and C-S-H decomposed, which causes internal crack propagation. A main fracture zone was formed in concrete after sufficient power input, creating a zone of concentrated damage. The fracture mainly occurred and propagated at aggregate–mortar interface. The study can provide a reference for the application of microwave-assisted concrete breaking.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"102 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141569","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}

Local tensile stress and linear elastic fracture mechanics are used to describe the propagation of microcrack. The orientation of bedding plane is also taken into account in damage evolution equation. The constitutive equations are developed by considering the coupling effects between the inherent and induced anisotropies. The model parameters can be determined by triaxial compression tests of rocks with different bedding orientations. The proposed model is applied to describe the mechanical behavior of a typical sedimentary rock. The experimental and simulated results are in good agreement. The model can capture the general anisotropic behavior and damage properties of the initially anisotropic rocks. Due to the crack-controlled model, snap-back behavior in the early softening regime is also captured.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"11 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145089627","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}

In response to this case, a five-dimensional digital twin model of the bogie frame with a new approach for accumulation fatigue damage is established.

To reveal the mechanism of external sulfate attack (ESA), a fully coupled nonlinear constitutive model is developed for transient diffusion-reaction-deformation response of concrete exposed to sulfate environment, by introducing the concentration of sulfate diffusion and the extents of multiple sulfate reactions as independent variables to characterize their respective contributions to free energy and volume expansion. In addition, a structural damage function is incorporated to measure the effect of ESA on elastic constants and diffusion coefficient of concrete. Specially, multiple reaction kinetics equations are established to satisfy the dissipation inequality, which depend not only on the concentrations of the species involved, but also on the stress. The model is then validated by comparing with the experimental results of one-dimensional sulfate attack, and numerical examples are used to illustrate the competing mechanisms between multiple reaction pathways and the interaction between chemical reactions and mechanical loading.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"25 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144899920","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}

Design codes generally assume concrete cone failure and do not cover plug failure. A new model for concrete at early ages is proposed based on continuum damage mechanics which can model both failure modes for cast-in headed anchors in early age concrete. The new damage model combines a modified power law for the onset of damage, an exponential softening law for the post-failure softening stage, and an additional modified power law to reproduce the final stages of fracture. The combined damage law is calibrated with three experimental tests for concrete at two different ages (43 hours and 14 days): uniaxial compression, Brazilian splitting tensile and wedge splitting tests. The new models are applied to investigate anchor pull-out failure to demonstrate that both cone and plug failure modes are produced depending on concrete age.

Addressing this gap, the pull-off fatigue crack (POF-C) model was built to predict crack propagation at these interfaces under pull-off cyclic loading. The model, based on continuum damage mechanics principles, integrates force equilibrium and dissipated strain energy equilibrium. Pull-off fatigue tests were conducted on interfaces using limestone, tuff, and basalt aggregates, with #70 matrix bitumen and styrene–butadiene–styrene copolymer-modified bitumen, at temperatures of 15°C and 20°C, and with bitumen film thicknesses ranging from 0.2 mm to 0.8 mm. Dynamic modulus and phase angle data informed the model inputs. Predicted crack sizes closely matched measured results on fractured surfaces, demonstrating less than 2% prediction error. Scanning electron microscope tests confirmed the model's validity, showing numerous circular mesh depressions on fracture surfaces. The POF-C model accurately forecasts POF-C lengths across varied conditions, revealing three distinct stages of crack propagation: a rapid growth (∼0.025 mm/cycle), a stable expansion stage (<0.025 mm/cycle), and a slow fatigue stage (∼0 mm/cycle). The fatigue mechanism involves the development of microdamage into microcracks, their nucleation and aggregation, and macrocrack throughout the entire bitumen–aggregate interface.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"15 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144747362","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}
