This paper presents a probabilistic analysis model for riveted lap joints with MSD. The probabilistic analysis model leverages a secondary customization of ABAQUS, enabling parametric modeling of penetration cracks with varying lengths. In this model, the stochastic processes of crack initiation, propagation, and failure are simulated through a Monte Carlo framework, incorporating the theories of fracture mechanics and fatigue statistics. In addition, a group of riveted lap joint tests are carried out to verify the accuracy of the calculation results. The simulated results are in good agreement with the mean experimental fatigue life. However, the model underestimates the dispersion observed in the experimental data in the current study, primarily due to the lack of extensive experimental data needed for further calibration. Overall, the developed model can capture the complex, interdependent mechanisms of fatigue damage in riveted lap joints with MSD.</p>\u0000 </div>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 9","pages":"3907-3924"},"PeriodicalIF":3.2,"publicationDate":"2025-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144773967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Obtaining stress intensity factor (SIF) is pivotal for the optimal design and safe usage of barbed sutures. In this study, an explicit method was proposed to calculate the SIFs for a barbed suture with Mode I crack under arbitrary stress distribution. The barbed suture was modeled as a round bar with different shapes of Mode I cracks. The shape coefficient, which was defined to describe the shape of crack, was computed using the point load weight function. Based on these shape coefficients, the basic stress intensity factors (BSIFs) for cracks under basic stress distributions, such as uniform, linear, and quadratic stress distributions, were determined. Then, the SIFs under arbitrary stress distributions were calculated through linear superposition of these BSIFs according to the corresponding stress distribution. The relative errors between the SIFs calculated by this method and the finite element are commonly within ± 8%. This demonstrates that the proposed explicit method is capable of directly and accurately calculating SIFs for round bars with Mode I cracks under arbitrary stress distributions, thereby avoiding the time-consuming processes of finite element analysis and numerical integration.</p>\u0000 </div>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 9","pages":"3815-3828"},"PeriodicalIF":3.2,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144774111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the widespread use of microbeam structures in movable components of microdevices, investigating their cyclic behavior under repeated bending is crucial. Therefore, three groups of single-crystal copper microbeams of different heights were fabricated using focused ion beam, and in situ cyclic bending experiments were performed in a scanning electron microscope to explore their complex plastic behavior. Results show that yield stress gradually decreases with increasing bending cycles due to strain gradient effects, with taller beams exhibiting a slower decline. The probability of burst size decreases gradually for microbeams of different heights in successive loading cycles, but the probability of burst size increases significantly in the final loading cycle due to the accumulation of dislocations near the neutral plane.
