本文分析了复合材料层合板的大挠度分析。基于von Karman意义下的一阶剪切变形理论，建立了弯曲问题的非线性控制方程。用离散奇异卷积(DSC)方法求解了这些方程。选择正则化的Shannon‘s Delta(RSD)核和Lagrange Delta Sequence(LDS)核作为奇异卷积。研究了层合板的长径比、纤维取向、边界条件、厚边比和外加荷载对层合板非线性静力响应的影响。
In this paper, large deflection analysis of laminated composite plates is analysed. Nonlinear governing equation for bending based on first-order shear deformation theory (FSDT) in the von Karman sense is presented. These equations have been solved by the method of discrete singular convolution (DSC). Regularized Shannon’s delta (RSD) kernel and Lagrange delta sequence (LDS) kernel are selected as singular convolution to illustrate the present algorithm. The effects of plate aspect ratio, fiber orientation, boundary conditions, thickness-to-side ratio, and applied load on the nonlinear static response of the laminated plate are investigated.
