摘要: In this work, a new finite element framework is developed and applied to the study modeling of ductile fracture mechanisms at microscale. More particularly, body-fitted meshing remeshing methodology introduced applications void coalescence are investigated. Though most studies focus on periodic arrangements voids, it was proven in experiments as simulations that random clusters have major influence growth coalescence. With method proposed paper, various can be addressed their effect studied large plastic strain stress states.
