摘要
将大型船舶的双层板架模型化为正交异性极，考虑横向剪切变形和材料非弹性的影响，提出了一种在弹性角约束边界条件下求解双层板架临界应力的方法。利用该方法，对几种特定边界条件下一系列的矩形权进行了屈曲计算，其结果与已有文献的解答相比吻合较好。
The double-wall grillage of a large scale ship is simplified to a orthotropic plates with transverse shear deformation. Allowing for the elastic angle constrains and the effect of inelasticity, a technique for rapidly calculating the critical stress of such orthotropic plates is proposed. With this technique, the critical stress of several kinds of rectangular plates are calculated. The comparison with other references shows good agreement.
