A Frictionless Contact Problem for Viscoelastic Materials
We consider a mathematical model which describes the contact between a deformable body and an obstacle, the so-called foundation. The body is assumed to have a viscoelastic behavior that we model with the KelvinVoigt constitutive law. The contact is frictionless and is modeled with the well-known Signorini condition in a form with a zero gap function. We present two alternative yet equivalent w...
متن کاملA Frictionless Contact Algorithm for Deformable Bodies
This article is devoted to the presentation of a new contact algorithm for bodies undergoing finite deformations. We only address the kinematic aspect of the contact problem, that is the numerical treatment of the non-intersection constraint. In consequence, mechanical aspects like friction, adhesion or wear are not investigated and we restrict our analysis to the simplest frictionless case. On...
متن کاملAn Error Estimator for Adaptive Frictionless Contact Finite Element Analysis
The derivation of an a posteriori error estimator for frictionless contact problems under the hypotheses of linear elastic behavior and infinitesimal deformation is presented. The approximated solution of this problem is obtained by using the Finite Element Method. A Penalization or Augmented-Lagrangian technique is used to deal with the unilateral boundary condition over the contact boundary. ...
متن کاملNumerical Analysis and Simulations of Quasistatic Frictionless Contact Problems
Contact phenomena among deformable bodies abound in industry and everyday life, and play an important role in structural and mechanical systems. The complicated surface structure, physics and chemistry involved in contact processes make it necessary to model them with highly complex and nonlinear initial-boundary value problems. Indeed, the now famous Signorini problem was formulated as an idea...
متن کاملAn Efficient Numerical Algorithm for Cracks Partly in Frictionless Contact
An algorithm for a loaded crack partly in frictionless contact is presented. The problem is nonlinear in the sense that the equations of linear elasticity are supplemented by certain contact inequalities. The location of a priori unknown contact zones and the solutions to the field equations must be determined simultaneously. The algorithm is based on a rapidly converging sequence of relaxed Fr...
