Micro Abstract:
Sheet bulk metal forming tools are often structured, either to favour material flow in desired directions, or to reduce the process forces. During continuous operation, the structures of the tools suffer from material wear which in turn effects the frictional behaviour that is responsible for the favoured flow directions.
In order to capture both effects numerically, this contribution presents a framework for the modelling of wear and the effective frictional behaviour of elastoplastic tools.
