Journal of Applied Mathematics, Volume 2003, Issue 2, Page 87-114, 2003., 2003 We consider the quasistatic Signoriniâ˛s contact problem with damage for elasticâviscoplastic bodies. The mechanical damage of the material, caused by excessive stress or strain, is described by a damage function whose evolution is modeled by an inclusion of parabolic type.

On the frictionless unilateral contact of two viscoelastic bodies
Journal of Applied Mathematics, Volume 2003, Issue 11, Page 575-603, 2003., 2003 We consider a mathematical model which describes the quasistatic contact between two deformable bodies. The bodies are assumed to have a viscoelastic behavior that we model with KelvinâVoigt constitutive law. The contact is frictionless and is modeled with the classical Signorini condition with zeroâgap function.

A frictionless contact problem for viscoelastic materials
Journal of Applied Mathematics, Volume 2, Issue 1, Page 1-21, 2002., 2002 We consider a mathematical model which describes the contact between a deformable body and an obstacle, the soâcalled foundation. The body is assumed to have a viscoelastic behavior that we model with the KelvinâVoigt constitutive law. The contact is frictionless and is modeled with the wellâknown Signorini condition in a form with a zero gap function.
