摘要 板材连续剪切变形技术(Continuous Confined Strip Shearing)以下简称C2S2是实现材料纯剪切变形的有效方法。介绍了C2S2的基本原理,对其所产生的剪切应变进行了计算和理论分析,并采用MAFAP4.0软件对其成形过程进行了模拟。模拟结果表明,通道转角Φ、外弧角Ψ等因素对材料的变形量有不同程度的影响。 C2S2 is an effective method to realize pure shear deformation. In this paper, the fundamental rule of C2S2 was introduced and the effective strain was analyzed, Moreover the software MAFAP4.0 was adopted to act the numerical simulation. The results show that the channel angle Ф and the curvature angle ψ have some degree impact on the deformation of materials.
