  A crystal plasticity-damage coupled finite element framework for predicting mechanical behavior and ductility limits of thin metal sheets 

  Article dans une revue avec comité de lecture

  ZHOU, S.; BEN BETTAIEB, Mohamed; ABED-MERAIM, Farid (2025-04)

  A new crystal plasticity finite element (CPFE) approach is developed to predict the mechanical behavior and ductility limits of thin metal sheets. Within this approach, a representative volume element (RVE) is chosen to ...
