Numerical optimisation of damage in extrusion processes

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 choices design variables, such as geometric parameters, and process parameters like friction coefficients or boundary conditions. strategy forward hollow extrusion. Compared extrusion, an additional variable, that is, mandrel radius, introduced into forming process, increases space.
