Description
The authors briefly describe a finite volume method for the numerical simulation of the evolution in time of ductile materials under an intense dynamic solicitation. They use the Wilkins model which describes the behaviour of a perfectly-plastic isotropic elastic material. The discretization scheme belongs to the category of centred Lagrangian methods with finite volume grids in which physical variables characterizing the flow are defined on a grid which follows the matter movement
