对称正交铺设矩形叠层板的非线性弯曲

本文应用1]中提出的奇异摄动方法,在3]的基础上,研究了在各种支承条件下承受均布载荷的对称正交铺设矩形叠层板的非线性弯曲问题,导出了挠度和应力函数的一致有效的N阶形式渐近解.对承受均布压力,边界位移为零的简支矩形板进行了分析、计算.

Nonlinear Bendings of Rectangular Symmetrically Laminated Cross-Ply Plates under Various Supports

This paper studies the nonlinear bendings of rectangular symmetrically laminated cross-ply plates subjected to uniform pressure under various supports on the basis of3] by the singular perturbation method offered in1]. The uniformly valid N-order asymptotic solutions of the deflection and stress function are derived. Analyses and numerical solutions are given for simply supported rectangular laminates, whase edge displacement is vanished.
