裂纹面受一对反平面集中力时裂纹线场的弹塑性分析

Near Crack Line Elastc Plastic Analysis of a Cracked Plate Loaded by Antiplane Point Forces

本文特采用线场分析方法对理想弹塑性Ⅲ型裂擦无限板裂纹面中点受一对集中力的情形进行弹塑性分析。本文的分析将完全放弃小范围屈服糸件，其结果在裂纹线附近足够精确。

The near crack line analysis method has been used in this paper to analyze the elastc plastic fea-ture of a center cracked plate with infinite demensions loaded by a pair of antiplane point forces at thecenter of the crack surfaces in a perfect elastc plastic material. The small scale yielding conditions havebeen abandoned,so the solutions are sufficiently precise.
