利用MSC.SuperForm软件对工业纯钛A路径ECAP二道次的变形进行模拟。获得了相应的载荷-行程曲线、等效应变和等效应力分布规律,并与一道次的模拟结果进行了比较,得出二道次挤压后等效应变的分布比一道次更均匀。
The deformation of industrial pure titanium A path ECAP two passes was simulated using MSC.SuperForm software. The corresponding load-stroke curve, equivalent strain and equivalent stress distribution are obtained and compared with the simulation results of one pass. The results show that the distribution of equivalent strain after two passes is more uniform than that of one pass.
