The experimental results showed that dissipated energy and the damage variable increased linearly with the number of loading-unloading cycles. The increase in initial damage results in greater creep strain, higher steady-state creep rate, and increased dissipated energy under the same creep loading, while reducing the long-term strength of the rock.

Using Abaqus/FE-SAFE simulations and LAC experiments, differences in surface quality and fatigue cycles under various laser parameters are observed. Results show that increasing the spot radius reduces heat accumulation and center temperature. A 1 mm radius yields a center temperature 5.58 times higher than a 7 mm radius and achieves a residual compressive stress of 412 MPa, which decreases to 198 MPa (51.9% reduction) at 7 mm. Larger laser power increases stress and fatigue life positively, while higher scan speeds reduce stress.

The phase-field method for fracture has proven to be a versatile tool for predicting unknown crack paths and failure mechanisms. In this contribution, we propose a phase-field model for fracture of periodic heterogeneous microstructures in a general finite strain setting. To overcome the bottleneck of scalability, we employ powerful and scalable solvers based on the fast Fourier transform (FFT). We demonstrate the capability of the model using the fundamental example of brittle fracture. A thorough comparison with conventional finite element method (FEM) reference results is carried out using a simple reference geometry. The results obtained show quantitative agreement between both numerical methods. Parameter studies provide recommendations for the choice of the numerical parameters. Following the comparison, we apply the FFT-based method to synthetic inhomogeneous microstructures, with a special emphasis of the investigation on scalability with increasing degrees of freedom and robustness of the method. The results of 2D and 3D simulations are promising, paving the way for future extensions in inverse materials design, for example, for metallic microstructures.</p>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 4","pages":"1782-1805"},"PeriodicalIF":3.1,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/ffe.14553","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581996","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}

Using digital image correlation and acoustic emission techniques, the research reveals that increasing thermal damage from 25°C to 800°C reduces granite tensile strength by up to 85.7% and induces a brittle-to-ductile transition. The NPR effect emerges, intensifies, and subsequently disappears as temperature increases, significantly altering stress distribution and deformation patterns. Local contraction zones created by the NPR effect can lead to overestimation of tensile strength in thermally damaged rock. Acoustic emission monitoring demonstrates a strong correlation between the NPR effect and microcrack development. These findings advance the understanding of rock mechanical behavior under thermal damage and provide practical insights for tensile strength evaluation in high-temperature geological settings, such as deep underground energy development and nuclear waste disposal.</p>\u0000 </div>","PeriodicalId":12298,"journal":{"name":"Fatigue & Fracture of Engineering Materials & Structures","volume":"48 4","pages":"1725-1740"},"PeriodicalIF":3.1,"publicationDate":"2025-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143581964","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}
