Dynamic Contact Problems for Viscoelastic Materials
Situations of contact between deformable bodies are very common in industry and everyday life such as train wheels with the rails, a shoe with the floor, tectonic plates, the car’s braking system, etc. Because of the importance of the contact problems, a considerable effort has been made in the modeling and numerical simulations, and the engineering literature concerning this topic is rather ex...
متن کاملAnalysis of Wear Phenomena in Sliding Contact Surfaces
A general approach to numerically simulating wear in rolling and sliding contacts is presented in this thesis. A simulation scheme is developed that calculates the wear at a detailed level. The removal of material follows Archard‟s wear law, which states that the reduction of volume is linearly proportional to the sliding distance, the normal load and the wear coefficient Careful attention is p...
متن کاملEvolution of Viscoelastic Contact Problems for Piezoelectric Materials with Adhesion
In this paper we consider a second order evolution inclusion with a coercive viscosity operator and a multivalued term of subdifferential form. The study is motivated by the dynamic problem of frictional contact between a viscoelastic piezoelectric deformable body and a foundation. The interaction between the body and the foundation is described, due to the skin effects, by a nonmonotone possib...
متن کاملAnalysis of thermo-mechanical wear problems for reciprocal punch sliding
The relative sliding motion of two elastic bodies in contact induces wear process and contact shape evolution. The transient process tends to a steady state occuring at fixed contact stress and strain distribution. This state corresponds to the minimum of the wear dissipation power. The optimality conditions of the functional provide the contact stress distribution and the wear rate compatible ...
متن کاملNumerical Analysis of a Quasistatic Problem of Sliding Frictional Contact with Wear
We consider numerical approximations of a quasistatic problem modeling the sliding frictional contact with wear between a viscoelastic body and a rigid moving foundation. The contact is modeled with the Coulomb's law of dry friction and the wear is described by a version of Archard's law. The variational formulation of the problem consists of a nonlinear evolutionary equation coupled with a tim...
