The stress intensity factor of a finite internally cracked stiffened plate with load on a crack surface

对裂纹表面作用分布力的含中心裂纹有限加筋板的应力强度因子进行了分析计算 .将含裂纹加筋板离散为边界受切向力作用的含裂纹板及受内力作用的筋条 ,由边界协调条件求解得到板的边界切向力 ,将含裂纹有限加筋板问题的求解转化为含裂纹有限板问题的求解 。

A finite internally cracked stiffened plate with load on a crack surface was studied. It is assumed that the tangential traction along two sides of the cracked plate is converted into the tension body force of the strip stiffener. After using the compatibility condition between the edge of the cracked plate and the strip, the final solution was obtainable. One numerical example was given.
