摘要
工程中常见含缝构件,在外力作用下裂缝会张开扩展,影响了构件的工作性能与整体结构。该文对含ⅠⅡ型复合裂纹构件的断裂进行了研究,并运用等效应力作为断裂判断依据,指出其计算结果与实验数据符合较好。
In engineering there are lots of members with crack. The crack will develop and open under external force which affect the function of the members and the whole structure.the critical condition and angle of crack expansion. These are presented and the least equivalent stress is studied as the fracture criterion. The theory results are well tally with the measured ones.
