作用于圆筒内壁裂纹面上的内压,以往在断裂力学分析中一般都予以忽略而未阐明理由。为此,本文对此效应作一估计。著名的HRR理论导出了下述方程和条
The internal pressure acting on the crack surface of the cylinder inner wall is generally ignored in the fracture mechanics analysis and the reasons are not clarified. To this end, this article makes an estimate of this effect. The well-known HRR theory leads to the following equation and bar
