弹性转动约束复合材料层合板的弯曲

Bending of Laminated Composite Plates with Edges Elastically Restrained Against Rotation

本文运用Ｒｅｄｄｙ［１］的高阶位移模式剪切变形理论，得出了具有弹性转动约束边界条件的正交对称铺设层合板的弯曲解。利用稀疏矩阵技术求解大型稀疏线性方程组。同三维弹性理论解相比，本方法所产生的误差很小。

Based on the Reddy-type plate theory of higher-order shear deformation ,a solution is formulated for symmetrically laminated cross-ply rectangular plate with edges elastically restrained against rotation.Large sparse system of linear equations are solved by sparse matrix methods.The present theory leads to less error when compared with three-dimensional elasticity solutions.
