【 摘 要 】

The process of severe plastic deformation of a copper specimen during dynamic channel-angular pressing is numerically investigated in a 3D statement for the dynamic scheme of loading. Computations have been carried out by the finite element method within the framework of the elastic-plastic medium model with allowance for fracture. Loading pressure and initial velocity values are determined to provide the possibility of the process of dynamic channel-angular pressing of copper specimens.
