摘　　要：本文提出自增强技术中求解最佳弹－塑性界面半径（ｒｊｏｐｔ）的解析式；研究了自增强对厚壁圆筒应力分布和承载能力的影响，并提出了自增强技术中的最佳内压．Based on the third and the fourth strength theory, this paper presents an analytic formula for optimum radius of elastic-plastic juncture in autofrettage technology; influence of autofrettage on stress distribution and load-bearing capacity of a cylinder is studied and optimum pressure in autofrettage technology is obtained.

关 键 词：压力容器 自增强 弹塑性 界面半径
