Most of mechanical systems and complex structures exhibit plate and shell components. Therefore, 2D simulation, based on plate and shell theory, appears as an appealing choice in structural analysis as it allows reducing the computational complexity. Nevertheless, this 2D framework fails for capturing rich physics compromising the usual hypotheses considered when deriving standard plate and shell theories. To circumvent, or at least alleviate this issue, authors proposed in their former works an in-plane–out-of-plane separated representation able to capture rich 3D behaviors while keeping the computational complexity the one of 2D simulations. In the present paper we propose an efficient integration of fully 3D descriptions into existing plate software.

计算结构力学中侵入最小的全3D分离板公式

大多数机械系统和复杂结构都具有板和壳组件。因此，基于板壳理论的2D模拟在结构分析中似乎是一个吸引人的选择，因为它可以降低计算复杂度。但是，此2D框架无法捕获丰富的物理特性，从而损害了推导出标准板壳理论时要考虑的通常假设。为了规避或至少缓解此问题，作者在以前的工作中提出了一种平面内-平面间分离的表示形式，该表示形式可以捕获丰富的3D行为，同时将计算复杂度保持为2D模拟之一。在本文中，我们提出将完整3D描述有效地集成到现有印版软件中的建议。
