Moving FE Formulations of Elastic-Plastic Steady Rolling Contact with CoulombFriction

摘要

This paper deals with the problem of elastic-plastic rolling contact with Coulombfriction. The moving FE formulations of steady rolling contact with Coloumb friction are presented on the basis of the transform between the fixed and the moving Lagrangian coordinate systems. It can be seen that based on such a transform the dynamic rolling frictional contact problem with spacially and time dependent can be equivalently transformed into the steady one with purely spacially dependent under some assumptions. The class of elastic-plastic infinitesimal deformational rolling frictional contact for an elastic rotating body with an elastic strip on a rigid foundation is taken into account. The mixed FE iterative algorithm based on Newton-Raphson method is used to solve the moving FE formulations proposed in this study. One example is given to demonstrate the effectiveness and validity of the moving FE formulations.
