NUMERICAL SIMULATIONS OF THE ECAP PROCESS. MULTI PASS

摘要

Numerical simulations of ECAP process carried out using DRACON code (VNIIEF) based on variation-difference method of solving continuum mechanics equations have shown that satisfactory agreement between experimental and numerical data on deformed billet state can be achieved by using experimental data in the development of physical model. An analysis of the influence of the number of passes on uniform state in ECAP has been performed.
