The model relies on the simultaneous fulfillment of two conditions: a non-local strain requirement and the discrete energy balance. The inputs of the model are strain and the stress intensity factor at failure, which depend on the number of cycles according to power law equations. The inputs can be obtained based on strain-life and stress intensity factor-life data from plain and notched specimens. The present approach is comprehensively validated against experimental datasets on additively manufactured samples from the literature for different materials, raster angles, notch geometries and loading conditions. Predictions by other approaches, such as Finite Fracture Mechanics (in its original stress formulation) and the Theory of Critical Distances, are also considered, for the sake of completeness. Results show that, in general, the proposed strain-based model is more accurate and provides consistently precise predictions across different cases.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-06-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10704-025-00855-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145143175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The case of simple shear is not defined separately. By using the difference in angles between the principal strain and principal stress axes, cases of coaxial stretch superposed with simple shear can be distinguished from cases of coaxial stretch without simple shear. In the case of anisotropic material or large elements, the distinction between these ambiguous cases can be utilized to optimize failure models. This study proposes a method to recover the deformation gradient and shear direction for proportional and non-proportional loading with an elastoplastic von Mises material.

The performances of two DIC-based techniques, namely, integrated-DIC and post-processing of DIC-measured displacement fields, are assessed on a benchmark test using fused deposit modeling capabilities, and are compared to a reference finite element solution. It is shown that Williams’ expansion remains valid on a large enough region around the crack to extract reliable SIFs even very close to the crack kink.

We validate the FCBM for the cPD model against experimental results from the literature on ductile failure in Al2021-351 alloy samples of various geometries. Notably, calibration of elastic and hardening material parameters is made only using the experimental data from the simplest geometry, a smooth round bar, and only up to the necking point. We then use that calibrated model beyond necking, through full failure, and for all the different sample geometries. The performance (speedup and memory allocation) of the new method is compared versus the meshfree method normally used to discretize PD models for fracture and damage. The proposed method leads to efficient large-scale peridynamic simulations of finite plastic deformations and ductile failure that are closer to experimental measurements in terms of displacement and plastic strain at failure than previous FEM-based solutions from the literature.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transgranular fracture occurred primarily in the reheated zone and in the as-welded zone with a dendritic microstructure inclined relative to the crack plane. With a dendritic microstructure aligned with the crack plane intergranular fracture occurred. The toughness of the as-welded zone with a low inclination angle, was significantly lower than that obtained in the other two weld zones. Due to the relatively large size of the zones compared to the fracture process zones of the tests, it is appropriate to characterize the failure behavior as large-scale heterogeneity.
