Finite Elements for Thermomechanical Contact and Adaptive Finite Elemnt Analysis of Contact Problems

摘要: This contribution is split into two parts. The first concerned with thermomechani-cal contact its continuous formulation, discretization and algorithmic treatment. second part associated adaptive finite element methods for problems which yield accurate thus reliable solutions within a prescribed error tolerance. To be most general we will derive geometrical model valid large deformations. Furthermore interface laws discussed the normal tangential stress components in area. Different variational formulations can applied to treat inequalities due contact. Of these different techniques, penalty method presented especially. of problem time space great importance has chosen regard nature problem.
