To clarify the underlying mechanisms, uniaxial compression tests were conducted on rock-like specimens with parallel holes (spacing: 0, 20, 40, and 60 mm) and prefabricated joints (dip angle: 0°, 30°, 45°, 60°, and 90°), with acoustic emission (AE) and digital image correlation (DIC) employed to monitor crack propagation and full-field strain evolution. Results show horizontal spacing affects specimen strength by regulating inter-hole stress superposition, with peak stress showing a nonmonotonic trend of first rising then falling and 20 to 40 mm spacing optimizing stress distribution to enhance load-bearing stability; joint dip angle dominates failure modes via crack propagation paths, as a 45° dip induces the strongest compression-shear coupling to maximize bearing capacity and increase mixed-mode cracks while shear cracks prevail at other angles. A boundary line with a slope of 100 enables quantitative distinction between different crack types, thus confirming the dynamic influence of these two parameters (horizontal spacing and joint dip angle) on crack modes. Additionally, numerical simulations conducted via COMSOL Multiphysics confirmed the existence of a “low-stress bridge” effect between the two parallel holes and elucidated the compression-shear coupling mechanism along the joint surface.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"43 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148288595","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 total damage is decomposed into fatigue damage and ratchetting-induced ductility damage. Within the framework of Lemaitre's continuum damage mechanics, combined with the cyclic stress–strain relationship and the evolution of ratchetting strain, the damage evolution equations and fatigue life prediction model are derived for specimens with different orientations by constructing an orientation tensor and a strength tensor, respectively. Finally, a relationship among the loading conditions, build orientation, and fatigue life is established. Comparison with experimental results demonstrates that the proposed model exhibits good prediction accuracy, providing a reliable theoretical support for the fatigue life assessment of additively manufactured titanium alloy components.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"28 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148288597","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}

They consist of intact rock or rock monolith and macro-damages, which include fractures, bedding planes, faults and other forms of discontinuity. It has been experimentally confirmed that with the increase of the rock mass scale, the mechanical properties of the rock mass decrease as a consequence of discontinuities. The subject of this paper is the analysis and determination of the scale effect on the damage plasticity model parameters, which describe the mechanical behaviour of the rock mass for different loads and scales. The scale effect is analysed on a constitutive model that can simulate the most complex mechanical behaviours in rock masses (elasto-plastic with damage in stiffness and strength). The analysis is based on the results of experimental tests of rock mass, which were carried out for different scales (scale of the rock mass sample in laboratory and scale of the in situ test – shear test), while the tests were performed at the same microlocation. For the considered experimental tests, appropriate finite element models (FEMs) were formed with boundary conditions that correspond to the ones from the experiments. By simulating the performed experiments with a series of FEM analyses with complex optimization algorithms, the parameters of damage plasticity model were determined for both values of the rock mass scale, proving the scale effect numerically. Based on the obtained results, analysis and discussion of the scale effect for a given rock mass were performed.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"1 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148288657","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}

To address the limitations of conventional mode-shape-based damage identification methods, which rely on baseline data and a large number of sensors, this article presents a novel approach based on response principal components under moving loads. Considering vehicle–bridge interaction, this study elucidates the composition of the response's principal components of damaged beams. Initially, the dynamic response of the beam is decomposed using the proper orthogonal decomposition, and the analytical expressions for the principal components of responses are derived. Then, damage identification is conducted, indicating that the principal components of the response for a damaged beam can be decomposed into modal components, dynamic components, and damage components. Moving average filtering is employed in the separation process, thereby extracting the damage component. Numerical simulations and experimental validations are subsequently conducted to assess algorithm performance. This study highlights the role of the damage component within principal components, providing new insights into their physical interpretation in structural damage identification.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"11 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148288688","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 this model, the fracturing process of each micro-spring is described as a barrier-crossing event where the effective barrier height depends on the external loading rate. Evolution of the reaction coordinate follows the Langevin dynamics. Solving the corresponding Fokker–Planck–Kolmogorov equation yields the failure probability of each micro-spring under dynamic loading, from which the dynamic fracture strain is derived. Numerical results demonstrate that the model naturally captures the characteristic two-stage strength enhancement of concrete: a gradual increase of dynamic increase factor at low strain rates, followed by a rapid rise beyond a critical threshold. By linking the static fracture strain of each micro-spring to its unique initial energy barrier, the model assigns distinct rate sensitivities to different material constituents. This approach enables the model to reflect different rate sensitivities in tension and compression without separate empirical adjustments. Finally, simulations of reinforced concrete beams under various loading velocities, including high-rate impact, validate the model's capability to predict structural dynamic responses in practical engineering scenarios.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"16 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148288658","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 aims to gain a deeper understanding of the dynamic response and failure mechanisms of ceramic composite ballistic plates under high-velocity bullet impacts. By combining ballistic experiments with numerical simulations, this article systematically investigates the dynamic response and damage mechanisms of SiC/UHMWPE composite ballistic plates subjected to high-velocity impacts from 7.62 × 54R mm armor-piercing incendiary rounds. A mirror-assisted 3D-DIC system was used to record full-field rear-surface deformation histories, from which the distinct stages of bulge evolution were quantitatively characterized. Independent validation was provided by high-speed oblique photography. For numerical simulation, the Johnson–Holmquist-2 constitutive model and the Peridynamics constitutive model were respectively applied to model the ceramic layer, enabling a systematic comparison of their performance in simulating ceramic damage behavior under high-speed impact. The study revealed the dynamic processes of stress wave propagation, crack initiation, and propagation within the ceramic following bullet impact. It clarified the formation mechanism of ceramic cones and radial cracks under the coupled action of compression waves and reflected tensile waves. This work provides crucial theoretical and experimental foundations for deepening the understanding of failure mechanisms in ceramic composite armor under impact loads and optimizing armor structural design.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"25 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148287351","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 IoT-assisted cooperative localization framework for UAV swarm traffic monitoring. It integrates IoT sensors, UAV-to-UAV, and UAV-to-infrastructure communication to enhance localization and task allocation. A DNN-assisted Butterfly Optimization Algorithm optimizes UAV trajectory planning and constraint handling efficiently. The DNN-assisted Butterfly Optimization Algorithm enhances trajectory planning by efficiently approximating nonlinear constraints and guiding the optimization process toward optimal solutions. Compared to conventional optimization methods, this approach improves convergence speed and solution quality, outperforming conventional optimization strategies in swarm coordination. The use of the Butterfly Optimization Algorithm (BOA) will optimize the trajectory of the UAVs by taking into account multiobjective performance constraints (i.e., energy consumption). Additionally, a deep learning-based method for approximating the complexity of trajectory constraints is employed to provide an enhanced optimization performance. Simulation results from a test case of 25 intersections and 50 road segments show that the proposed framework can achieve up to 27% reduction in localization error, 32% improvement in coverage efficiency, and 18% reduction in the energy consumed by the UAV compared to the conventional GPS-based methods for UAV deployment. The proposed IoT-assisted UAV system is scalable, efficient, and capable of providing robust real-time traffic surveillance in Smart City environments. The proposed framework follows a structured workflow involving data acquisition from IoT sensors, real-time data processing, and cooperative localization through multisource information fusion. This enables accurate positioning and efficient monitoring, ensuring efficient real-time traffic monitoring and localization.","PeriodicalId":13837,"journal":{"name":"International Journal of Damage Mechanics","volume":"2 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2026-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148287353","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}
