The extrusion process of the belt is a in which and inner bore barrel undergo complex contact collision, rifling gradually penetrates belt, so that material continues to fail destroy. It has high instantaneous, strong impact, temperature, high-speed change. There big gap between existing theory actual process, it urgent carry out research work on this problem. This paper analyzes basic characte...

Abstract Numerical optimisation is applied to rod extrusion in order generate optimal parameter sets which result reduced damage accumulation. A brief overview of academic applications for given. Their restrictions are reflected upon, leading the proposed framework utilising commercial software Abaqus FEA, enables industrial problems with frictional contact. The setup modularly enable arbitrary...
