| 摘 要： | 本文研究了正交各向异性混杂叠层梁的应力与变形计算.叠层梁是由几层弹性性质明显不同的非均质子层梁组成.对每一子层梁应用剪切理论,并假设相邻子层梁的交界面是理想连接.文中导出了关于子层梁剪切转角ψi的二阶常微分方程组.求解微分方程组可得到叠层梁应力与位移关于剪切转角的ψi解析表达式.叠层梁组分材料中任一点应力可按有效模量理论和整体——局部方法[3]求得.

| Abstract: | In this paper the stress and deformation in a orthotropic hybrid laminated beam are studied. The laminated beam consists of some nonhomo-geneous sub-layers, the elasticity of which is significantly different. The shear theory is applied to each sub-layers and the perfect bonding is assu-med in the interface between adjoining sub-layers. In this paper, a set of second-order ordinary differential equations with respect to the unknown rotation angle of each sub-layer is established. Solving the differential equa-tions, the displacement and stress can be analytically obtained. The stress in component materials can be determined by use of the effective modulus theory and global-local method. |
