In this dissertation, the collapse strength of casing with crescent-shaped wear was analyzed with finite element method as plane or spatial problem.

The calculation case shows that the result of collapse strength calculated by using the triaxial stress circle theory is bigger than that by other theories.

通过实例计算，对比分析了用三向应力圆理论与其他几种理论计算的抗挤强度值。结果表明，应用三向应力圆理论计算的值偏大。

The critical load and the equivalent collapse strength are defined respectively according to its long displacement features and strength features under non-uniform loads.

并依其非均匀载荷下的大位移特征和强度特征，分别定义了临界载荷和等效抗挤强度。
