空心旋转圆盘的弹塑性位移分析

The Elasticl—Plastic Displacement Analysis of Rotating Hollow Disk

本文对理想性材料等厚度空心旋转圆盘进行了位移分析,得到其弹塑性位移场的解析解,并对各种不同外内半径比的空心旋转圆盘作了计算机位移分析,得到弹塑性位移与弹性位移属同一数量级的结论.

This paper makes a displacement analysis of the rotating hollow disk made of elastic per- fectly—plastic material amd gets the analytic solution of its elastic—plastic displacement field.In addition,with the help of comput,it makes the displaceement analysis of the rotating hollow disk with all kinds of the outside and inside radius and comes to the conclusion that the elastic—plastic displacement is in the same order of magnitude as the elastic displacement.
