摘要

采用三维动态加载方案，对钛试件在动态通道-角挤压过程中的剧烈塑性变形进行了数值研究。在考虑断裂的弹塑性介质模型框架下，采用有限元方法进行了计算。确定了钛试样的初始速度和加载压力的有效值。

Numerical simulation of dynamic channel-angular pressing processes

Severe plastic deformation of a titanium specimen during dynamic channel-angular pressing was numerically investigated in 3D statement for 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. The effective values of initial velocity and loading pressure are determined for the titanium specimen.
