Superposition of the autofrettage residual stress distribution and working load stress distribution is combined with ANSYS Separating Morphing and Adaptive Remeshing Technology (SMART) to determine the effective stress intensity factor as the crack grows. The condition for crack arrest is identified by comparison with a crack arrest model defining the crack propagation threshold stress intensity factor range for microstructurally short, physically short, and long cracks. The crack propagation threshold models of El Haddad and Chapetti are implemented and applied to fatigue analysis of stainless steel and low carbon steel double notch tensile test specimens with preinduced compressive residual stress. Based on comparison with fatigue test results, the Chapetti model is selected for use in the analysis of a 3D aluminum alloy valve body. The calculated minimum autofrettage pressure required to give crack arrest under a given working load cycle is found to be in good agreement with experimental observations from the literature.</p>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 3","pages":"1272-1287"},"PeriodicalIF":3.1,"publicationDate":"2024-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ffe.14539","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143120492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article uses the phase-field model to investigate the impact of thickness on elastic–plastic metallic materials. Initially, the fracture toughness of metallic materials in three dimensions is calculated under elastic deformation. The findings reveal that the outcomes obtained from the phase-field model remain consistent regardless of thickness, thus confirming its effectiveness. Subsequently, the study delves into the three-dimensional fracture behavior of metallic materials during plastic deformation. It illustrates how the phase–field model approach enables a thorough simulation of crack propagation within these materials, offering a comprehensive understanding of their fracture behavior. By analyzing the phase-field contour, the thickness effects of three-point bending specimens during crack growth are effectively captured. In addition, the dimensionless fracture toughness ratio trends with thickness are compared between phase-field modeling and experimental results in the open literature, showing good agreement.</p>\u0000 </div>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 3","pages":"1215-1235"},"PeriodicalIF":3.1,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143117994","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}

Stress-based fracture-related variables of the specimens with 10 different structures for WE43 alloy are captured, and the hardening behavior is with some strength differential effect. These fracture stresses have a strong sensitiveness to stress triaxiality and Lode parameter. Fracture loci of WE43 alloy are constructed by the proposed model with the smaller prediction error of 0.25683 than the stress-based DF2016 fracture model (0.527).

To correlate the resulting diffraction patterns with various dislocation arrangements of both metals, fatigue tests were carried out up to certain numbers of cycles and at predetermined plastic strain amplitudes. The differences in dislocation microstructure and internal stress distributions give rise to an appreciable change in the peak shape of Laue reflections, leading to unique characteristics in the respective diffraction patterns.

Significant changes in Shannon entropy were observed before fracture failure, suggesting it as a reliable precursor indicator. The study found that as loading rates increased, the time for CSTBD to undergo plastic deformation decreased, leading to more transgranular and intergranular fractures. Surface morphology analysis revealed that fractal dimensions and surface roughness (Rrms) increased with higher loading rates.
