Abstract
The main features of a lagrangian approach are briefly
introduced. Illustrations are given through numerical solutions concerning the
case of kinematics endowed with the spherical symmetry. Several types of
constitutive behaviours are taken into account, namely those of linear or
nonlinear elasticity, of linear or nonlinear viscoelasticity, of plasticity and of viscoplasticity. In general, the strains, the strain rates and the rates of
strain rate are ranging from .1 to 1, from 103 to 104
s-1 and from 108 to 1010 s-2,
respectively.
