To address this issue, an enhanced framework is developed to model elastic–plastic stress and strain distributions near a crack tip. Building on previous work, the framework employs the deviatoric forms of Hencky’s plasticity equations and the multiaxial Neuber method by excluding effects of hydrostatic stresses for greater accuracy. A key innovation is the introduction of a variable stress re-distribution factor, which captures spatial variations in stress re-distribution due to plastic deformation near a crack tip. This innovation replaces the earlier assumption of a constant factor by offering a more realistic representation of stress fields. The framework was verified by using non-linear FE analysis based on two distinct hardening behaviors of SAE 1045 steel plates with 2 mm and 4 mm crack lengths to evaluate the model’s robustness across diverse non-linear hardening behaviors and its ability to handle varying crack sizes. The results demonstrate the framework’s superior accuracy compared to the previous model. This approach provides a practical and reliable alternative to FE analysis with promising applications in fatigue life assessment and fatigue crack growth analysis under cyclic loading conditions.</div></div>","PeriodicalId":14112,"journal":{"name":"International Journal of Fatigue","volume":"193 ","pages":"Article 108792"},"PeriodicalIF":5.7,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142929648","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}

When Ti content is 0.087 %, the number of micro-cracks and micro-pores in the fatigue fracture specimens of WSWJ is the smallest, indicating the least fatigue damage. During cyclic plastic deformation, the dislocation cell structures occur in the weld metal, significantly reducing the high dislocation density microstructure. As a result, the proportion of recrystallized microstructure increases.

When Ti content is reduced to 0.044 %, the composite precipitation composed of Ti-rich phase and Mn-rich phase can significantly hinder the dislocation movement. Additionally, the degree of grain preferred orientation and the resistance of dislocation slip increase, resulting in the increase in fatigue damage. When Ti content increases to 0.14 %, the dislocation walls are connected to form a network structure, and the relatively large precipitations are distributed around this structure.
