To this end, first, the proposed model is validated against two experimental three-point bending benchmark problems with different material functions as well as varying loading rates and durations. Then, numerous additional cases with different boundary conditions and material distribution are studied to predict crack initiation and propagation in such mediums. The examples consist of three-point bending and Kalthoff–Winkler specimens with various material functions under dynamic loads. Finally, the effects of material anisotropy induced by functionally varying material properties on crack propagation path are addressed. It is shown that this new model is advantageous because of its capability to account for shear deformation effects in the bonds previously ignored by the original bond-based peridynamic models. Moreover, comparing the proposed modified bond-based model to more complex methods, such as state-based peridynamics, reveals that the simplicity of the current approach results in lower computational costs while still achieving comparable results.</p>\u0000 </div>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 5","pages":"2191-2205"},"PeriodicalIF":3.1,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143787285","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}

This study investigates the UHCF properties of the Ti6Al4V alloy by evaluating microstructure variations and provides insights into the mechanism of nanograin formation and expansion in the internal crack initiation sites. Key findings indicate that a partially recrystallized microstructure (annealed at 650°C) exhibits the highest fatigue life, with enhanced resistance to crack initiation attributed to elongated α grains, moderate texture intensity, and optimal basal slip activation. Internal small-scale inclusions, which precede deformed α grains, can also serve as initiation sites for cracks in the UHCF regime. The formation of nanograins at crack initiation sites is primarily driven by the slip of basal <a> dislocations, with their subsequent growth influenced by the type of surrounding grain boundaries.
