任意铺设纤维增强型复合材料层合板具有高阶剪切时的非线性弯曲

Nonlinear Bending of Wilfully Lied Fibre Reinforced Composite Laminates with Higher-Order Shear Deformations

本文利用变分原理,在Rcddy高阶横向剪切变形理论的基础上,建立了任意铺设纤维增强型层合板的非线性弯曲的基本方程。由所建立的方程,作者用广义三角级数计算了在均布载荷作用下,四周固支的对称角铺设叠层厚板的非线性弯曲,并得出了解析解。

Using variantional methods,on the basis of Reddy's linear higher-order shear deformations theo- ry,establishes the governing equations of nonlinear bending on wilfully lied fibre reinforced laminates. On the basis of governing equations,solves the problem of the nonlinear bending of the symmetric angle-ply laminated rectangular plates under uniformly lateral distributed loads with rigidly clamped edges by generalized trigonometric series,and gains analytic solutions.
