An improved « plastic wave » friction model for rough contact in axisymmetric modeling of bulk forming processes
Source abstract
Abstract
In the case of a rough contact without friction between axisymmetric billets and punches, experimental evidences as well as very fine numerical modelling show that the workpiece material flows as a lubricant layer in the vicinity of the contact surface. As no existing friction laws used for bulk forming processes can take into account this typical surface behaviour, an improvement of the so-called “plastic wave” friction law is proposed in order to describe more accurately the plastic flow in the workpiece-tool interface.
