摘要: 本文在完全放弃了小范围屈服条件的情况下,采用线场分析方法对理想弹塑性Ⅲ型边裂纹无限板裂纹面受一时集中力的情形进行了分析。其结果在裂纹线附近足够精确,通过一合理假定,本文还对Ⅲ型边裂纹有限宽板裂纹面受一对集中力的情形进行了分析。

Abstract: In this paper,the small scale yielding conditions liave been abandoned。By using the near crackline anaIYsis method,the plastoelastic solutions,which are sufficiently precise near the crack line,havebeen obtained for a mode Ⅲedge cracked plate with infinite demensions loaded by point forces in per-fect plastoelastic material;Through a reasonable assumption,mode Ⅲedge cracked plate with finite de-mensions loadeo by Doint forces,has also been analysed.

Key words: mode Ⅲedge crack, near crack line analysis, point force, plastoelaltic beundary, plastoelas-tic fields
