The comprehension of the fundamental mechanisms controlling the evolution and mutual interactions of extended defects such as dislocation and cavities is crucial to understand the behaviour of materials under extreme conditions. Underlying phenomena

This thesis was dedicated to the development of a relevant numerical tool to predict the fracture in 3D porous ceramics such as the electrodes of Solid Oxide cells (SOCs). For this purpose, the so-called phase-field method (PFM) was adopted. Indeed,

Ce travail porte sur la modélisation à l'échelle microscopique de la rupture transverse de composites à matrice céramique (CMC). On cherche en particulier à mettre en évidence par la simulation l'influence de la répartition des fibres sur la

This work presents a study in non-linear mechanics, in the classical framework of brittle fracture in heterogeneous media. We study numerically the localization and propagation of damage in a triamino-trinitrobenzene-based (TATB) material under vario

Recently, the phase-field method has been intensively developed to model and simulate the nucleation and propagation of cracks in materials and structures in a variety of situations. In this development, many questions remain still open and a lot of
