Abstract We assessed the suitability of the Material Point Method (MPM) to simulate the equal channel angular pressing technique (ECAP). This severe plastic deformation process combines several interesting and challenging features in the context of numerical simulations, namely large displacements, large plastic deformations, as well as abrupt contact changes between the rigid tools and the work piece. Moreover, ECAP has been intensively studied, experimentally, numerically and theoretically, which makes it an ideal benchmark for testing MPM. Results from finite element analysis are also presented for comparison to MPM because this method is widely considered as a robust and reliable computational technique… More >
