I am trying to do a finite element analysis ofcold extrusion process of a tube wherein the steel tube is reduced from a larger outer diamter to a smaller one by extrusion process.The tube is held stationary and the die is pushed into the tube for a particular length and then retrieved.I am interested in finding the residual stress distribution after extrusion. Do i have to take the stress state after the removal of die as residual stress or do i have to perform a spring back analysis after removing the die and then consider the resulting stress state as residual stress? Is there a procedure to estimate the residual stress by FEA.Any help in this regards will be highly appreciated.(adsbygoogle = window.adsbygoogle || []).push({});
