摘要
对等径侧向挤压变形的应变进行了深入的分析，应用平面纯剪切变形应变分析的结果，得到了等径侧向挤压变形真应变和等效真应变的计算公式，分析了循环等径s型侧向挤压真应变和等效真应变的变化规律。
In this paper,the strain of the equal-cross section lateral extrusion has been analyzed,and the true strain and equivalent true strain formulae are derived from the strain analysis of the plane-pureshear deformation.At the same time,the tendency of true strain and equivalent true strain of the cyclic S-type lateral extrusion have been studied.
