摘要
本文对自增强和非自增强带裂纹厚壁圆筒的疲劳寿命提出计算方法,其计算结果与试验相符。试验结果表明,自增强处理能提高带裂纹厚壁圆筒和焊缝的疲劳寿命。
The authors propose a fatigue life calculation for autofrettaged and nonautofrettaged cracked thick-walled cylinders.This calcu- lation is in agreement with the experimental results.The experi- mental results indicate that autofrettage can increase the fatigue lives of the cracked thick-walled cylinders and welded seams.
