一种分析对称铺设层合板的新方法

A NEW METHOD FOR ANALYSIS OF SYMMETRY LAMINATED PLATES

本文对多层纤维对称铺设层合板的分析提出了一种新方法。此方法以假设板厚方向横向剪应力分布为前提,来建立层合板的微分方程组。其特点是反映了层合板间剪应变跳跃式变化这一实际情况,满足层间剪应力平衡条件。文章通过算例说明此法对分析层间剪切刚度较低的层合板简便、有效。

In the present new method for analysis of symmetry laminated plates, the distributions of transverse shearing streses in thickness are first assumed, and then their differential equations are derived. The method characterizes the discontinuity of transverse shearing strains between layers and fulfills the equilibrium conditions of stresses between layers. Numerical results shows the method is reliable and simple for analysis of laminated platbs.
