Abstract

The objective of this paper is to provide an overview of current research into computational modelling techniques that are being developed to simplify and expand the industrial use of the finite element simulation of metal forming processes. The improvement of tool and process design and the reduction in development times require computational tools that are easy to use, provide results rapidly and give accurate data not only in terms of deformed shape and die filling but also in terms of product quality and structure. This paper provides a summary of four areas of current development. These are: (a) simplified computational modelling tools for fastener forming, (b) remeshing techniques for ring rolling simulation, (c) models for microstructural evolution in forming stainless steel, (d) modelling of surface dimpling effects in cold roll forming. The paper concentrates on current research within the Solid Mechanics and Process Modelling Group at the University of Birmingham, but this represents only a small fraction of current worldwide activity in this area.
