【摘要】 本文使用Ｆｏｕｒｉｅｒ积分变换，对非对称载荷作用下的Ｇｒｉｆｆｉｔｈ裂纹问题进行了研究。利用裂纹两侧的位移和应力联结条件，将问题归结为一组带Ｃａｕｃｈｙ核的奇异积分方程，通过Ｃａｕｃｈｙ反演求得了问题的精确解，在此基础上．给出了其应力强度因子的表达式。该结果可作为基本解用于求解一般裂纹系问题。更多还原

【Abstract】 in this paper,by using Fourer integral transform,we try to investigate the problem of a Griffith crack loaded by asymmetrical distribution of surface tractions. According to the joined conditions of the crack.the problem can be reduced to a set of Cauchy singular integral equations,then the exact solutions is obtained by making use of Cauchy reversal operations,and the stress intensity factors are given.The results may be used as fundamental solutions to solve a general crack system of plane.更多还原
