J. Bonini et al., IMPROVING CONTACT-FRICTION CONDITIONS IN DYNAMIC SIMULATIONS - APPLICATION TO THE TAYLOR IMPACT TEST, Journal de physique. IV, 7(C3), 1997, pp. 797-802
The aim of this work is to test new contact-friction modelling by mean
s 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 calculat
ion of the contact forces with all the other links of the mechanical s
ystem.
