Finite Element Analysis of Elasto-Viscoplastic Dynamic Rolling Contact withCoulomb Friction. 1. Theory

摘要

This paper deals with the problem of elasto-viscoplastic dynamic rolling contactwith Coulomb friction. The moving FE formulations of dynamic rolling contact with Coloumb friction are presented on the basis of the transform between the fixed and the moving Lagrangian coordinate systems. The class of elasto-viscoplastic infinitesimal deformational rolling frictional contact for an elastic rotating body with an elastic strip on an elastic foundation is taken into account. The mixed FE algorithm based on Newmark integration scheme is used to solve the moving FE formulations proposed in this study.
