含轴向内部裂纹圆筒的标准载荷及其应用

The Normalised Load and Application for Pressurized Cylinder with Internal Axial Crack

通过分析含轴向内部裂纹圆筒的h_1～n曲线,给出了这种裂纹体的标准载荷和关于应变硬化指数的拓宽范围内的估算公式。并且通过例子进一步说明了具体应用这一估算公式的方法。

Through the analysis of h_1~n curve for cylinder with an internal axial crack, this paper determines the normalised load for this cracked body, and gives the estimation formula of strain hardening exponent in a widened interval. An example of applying the estimation formula is explained in detail.
