SIMULATION OF ROLLING BY ELASTOPLASTIC CONTACT BOUNDARY ELEMENT METHOD

Abstract In this paper, a new method named elastoplastic contact boundary element method developed by the authors of this paper is used in the simulation of rolling process. As the roller is an elastic body, and workpiece is made of a kind of elastoplastic material, the rolling process can be taken as an elastoplastic contact problem. The least assumption is considered in simulating the rolling process, therefore, an effective and accurate numerical approach is presented for analysing the rolling process.
