摘要

应力强度因子作为表征裂纹尖端应力场强弱和断裂分析的一个重要参量,其简单而有效的求解方法具有重要的工程实际意义。利用J,2,守恒积分建立了一个求解弯曲载荷作用下圆柱壳环向周期裂纹应力强度因子的计算方法。该方法原理清晰,计算简单。

Abstract

Stress intensity factor is an important parameter that characterizes the stress field near the tip in fracture analysis. The simple and effective methods to estimate intensity factor become significant. Based on the J,2, conservation integral, a simple exact method is proposed to determine the stress intensity factor for periodic cracked pipe under the bending effect. The principle of this method is clear and the calculation process is simple.
