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}

In this paper, the effect of HTHP aging on the fatigue damage characteristics of HNBR in an oil-based mud environment is investigated through experiments and numerical simulations. The experimental results showed that the elongation at break of the specimens decreased by 260% and the compressive stiffness increased with strain after high-temperature and high-pressure exposure in the oil-based mud. Furthermore, tear tests showed that the rate at which the aged HNBR produced unit crack surfaces was significantly accelerated.
