Термоупругий осесимметричный конечный элемент для решения контактных задач цилиндрических оболочек

Abstract

This paper is dedicated to a coupled thermoelastic axisymmetric finite element suitable for solution of contact problems. Consideration of transversal deformation delivers physically based contact stiffness matrix. This formulation leads to an unsymmetrical system of equations. Comparison between analytical and numerical solution of test problems is presented.
