Variational and numerical analysis of the Signorini's contact problem in viscoplasticity with damage.
An a posteriori error analysis for dynamic viscoelastic problems
In this paper, a dynamic viscoelastic problem is numerically studied. The variational problem is written in terms of the velocity field and it leads to a parabolic linear variational equation. A fully discrete scheme is introduced by using the finite element method to approximate the spatial variable and an Euler scheme to discretize time derivatives. An error estimates result is recalled, from which the linear convergence is derived under suitable regularity conditions. Then, an error analysis...
