摘要
ECAP(EqualChannelAngularExtrusion)方法 ,是实现材料纯剪切变形的有效方法。本文采用有限元 (FEA)分析软件ANSYS对A1的挤压过程进行仿真与分析。分析结果表明 :外切角 ψ、圆角半径、试样与凹模之间的摩擦系数、凹模本身的特性 (如弹性模量、泊松比等 )等等 。
ECAP(Equal Channel Angular Extrusion)is an effective method realizing pure shear deformation.In this paper,adopting FEA software Ansys to simulation and analysis the process of extrusion.The results show:die corner anagle ψ,the radius of round angle,the friction coffience of workpiece and die,the properties of die(elastic modulus,possion ratio)et al,have some degree impact on the deformation of materials.
