| 摘 要： | 从板的经典理论出发，导出了两对边简支，另两对边自由的正交异性矩形板，在自由边上受单位集中力矩作用时的Ｇｒｅｅｎ函数。以此作为基本解，应用边界积分法求得了两对边简支，另两对边自由，在垂直于简支边的对称线上有穿透裂纹的正交异性板在该对称线上的弯矩。

| Abstract: | In the paper, Green function of orthotropic plates with two simply-supported opposite edges and two free edges under unit concentra-ted bending movement acting at a free edges is derived from Krichhoff's theory. Based on the fundamental solutiun presented, the bending moments along the symmetrical axis of the plates with crack are obtained by means of the BEM. Furthermore , solution by means of method presentod in this paper and experimental data with SMC-D plates as samples are compared and the maxium error is 17.3%. Therefore, the solution presented here is applicable to the cracked SMC-D plates when measurment of the plastic area is less than 1mm. |
