摘要: 本文提出了在光塑性技术中,用Almansi应变张量进行一般三维应变分解的方法,给出了Almansi应变——光学定律,并对圆柱微粗及阶梯轴楔横轧的三维应变场进行了尝试求解。

Abstract: A method for resolution of the general 3-D strain in photo plastic techniques using Almont’s strain tensor is presented. The Almansi Strain-Optic Law is given and the resolution of 3-D strain fields of an upset cylinder and a transverse wedge rolled shaft is also tried in this paper.
