摘要
推导出几何非线性和物理非线性且存在初始缺陷的矩形薄板在纵向荷载作用下增量形式的基本微分方程，并用伽辽金配点法求解该方程。数值计算结果与已有文献的理论和实验结果相当一致。
The incremental governing differential equations of rectangular plates with geometric and materialnonlinearities as well as initial imperfections, which subjected to in-plane compression . are derived inthis paper, and are solved by Galerkin-collocation method. The numerical calculations show that theresults of this paper are in good agreement with those of theory and experiment obtained by other au-thors.
