A level-set and anisotropic adaptive remeshing strategy for the modeling of void growth under large plastic strain

Abstract : A numerical model based on the use of a level set framework coupled with an anisotropic re-meshing technique is presented in order to describe the void growth process for 2D and 3D configurations. Interfaces of inclusions and voids are described implicitly using level set functions. An anisotropic meshing - remeshing strategy is employed to track interfaces and ensure the accuracy of finite element calculations. The matrix and inclusions are elastic-plastic materials. The numerical methodology is adopted to study the effect of different parameters such as void or inclusion orientation and domain size. A good agreement is found with available experimental data and those found in the literature. The proposed method is shown to be an efficient promising technique to study ductile damage stages as void nucleation and growth. A demonstration of the method potential is illustrated by studying void growth for a 2D real complex microstructure and for a simple 3D microstructure
