摘要
层合结构已广泛地应用于各类工程领域。文中介绍的三维虚拟层合板壳单元,其主要特点是它允许同一单元由不同材料构成,有限元网格划分时可以把整体节点定义在结构的外部。这就使得该单元不仅可以应用于一般的层合结构计算,而且还可以应用于结构的形状优化设计。文中的经典算例说明了该单元的有效性。
The laminated composite structure has been found in wide application for vast kinds of engineering. In this paper, 3D virtual laminated plate-shell element was presented. The element permits same element to be made of different materials. The nodes in total coordinate could be defined outside of the solid structure. Therefore, the element can be applied to general laminated composite structure, and also to shape optimization. The following classical cases show the validity of the element,,
