TL;DR: In this paper, a new multi-phase field method is developed for modeling the fracture of polycrystals at the mi-crostructural level, where inter and transgranular cracking, as well as anisotropic effects of both elasticity and preferential cleavage directions within each randomly oriented crystal are taken into account.

TL;DR: In this paper, a phase field model is proposed to reproduce non-free anisotropic crack bifurcation within a framework allowing for robust and fast numerical simulations, and its ability to capture the thought phenomenon is illustrated through several examples.

TL;DR: A Local/global non-intrusive coupling algorithm is proposed for the analysis of mixed-mode crack propagation that couples a linear elastic global model with an enhanced local model capable of modeling a crack and accurately estimating SIFs.

TL;DR: In this article, a combined experimental and numerical study is presented in order to predict fretting crack propagation, with carefully controlled loading conditions leading to cracking as the main material response, extraction of 2D and 3D crack geometry from post-mortem cross-sections, a three-dimensional X-FEM model based on a three field weak formulation accounting for 3D non-planar frictional crack and the level set formalism authorising a direct use of actual reconstructed crack shape, the stress intensity factors quantification, a mixed mode Paris law identification and finally the crack growth simulation.

TL;DR: In this article, the phase transition model for material dissolution is coupled with the mechanical problem in a robust manner, providing an efficient tool for studying the competition between electrochemical and mechanical contributions to fracture.
