The aim of this work is to test new contact-friction modelling by means of the elastoplastic Taylor impact-test. The contact-impact Lagrange multiplier method is developped in a dynamic explicit finite element frame. It allows the continuity of the contact conditions without the definition of any shock stiffness. This technique couples the calculation of the contact forces with all the other links of the mechanical system.
