Abstract:Equal-Channel Angular Pressing(ECAP) is a method for fabricating bulk ultra-fine grain material by way of simple shear deformation.In this paper,non-linear finite element software MSC.Marc is used to simulate the deformation process of pure aluminum undergoing ECAP.The distribution of equal effective strain and equal effective stress is obtained through numerical simulation.The variation of pressing load versus deformation time and the influence of friction on ECAP are analyzed.
Keywords:equal-channel angular pressing   numerical simulation  finite element
