摘要
采用视塑性方法研究等通道转角挤压变形规律。通过观测试样变形平面上网格结点的位移来确定等通道转角挤压中金属流动变形规律 。
The deformation regularity of the equal channel angular extrusion is investigated by using vision plasticity method And the metal flowing feature in the course of the equal channel angular extrusion is determined by displacement observation of the mesh nodes of samples on the deformed plane The range of the deformation region and the distribution of shear strain on the equal channel angular extrusion are also deal with
