摘要
正交各向异性多层夹芯层板具有较好的强度、刚度和稳定综合性能,已在一些重要承力结构(如复合材料桥)中应用。本文建立的分析理论,考虑板层和芯层为正交各向异性,各层材性和厚度可以不同,各芯层角变形可以不等的较普遍情况,而目前流行的单夹芯板的Hoff理论和Reissner理论只是本理论简化的一种特殊情况。
The orthogoi al multilayer sandwich plate which provides considerable strength, stiffness and stability has been used in some important engineering structures, such as the composite material bridge. The analytical theory proposed in this paper is based on the multilayer sandwich plate consisting of orthogonal decks and cores with various thickness and different shear deformations in cores, and the theory posseses generality in nature. It can be readily shown that Hoff’s theory and Reissner’s theory are merely the particular cases of multilayer sandwich plate when reduced to the single layer condition.
