Virtual prototyping of radial extruded components

摘要

A finite element model was used to exploit some evidence, given by early investigations, of the possibility of achieving sufficiently large plastic deformation of tubes, to enable the production of certain engineering components, by extrusion into a die-cavity. The importance of including special features in the model like mesh adaptivity is stressed. A real part for the automobile industry was designed, by virtual prototyping, to be forged by this technique and a comparison is made with the traditional forging from solid rods.
