摘要

在本研究中，提出了一种新的四边形单元，即SQ4C，结合Timoshenko梁单元，用于加筋板壳结构的静力和屈曲分析。这些元素背后的思想是对剪切锁定和膜锁定的处理，这些锁锁是由一阶剪切变形理论和曲面壳几何网格的框架产生的。对于一般情况，本文也给出了带偏心的计算公式。给出了静力和屈曲分析解，并与其他可用的数值解进行了比较，以说明所提出的单元对加筋板壳结构的鲁棒性。本文也有助于工程师补充他们的知识。

Static and buckling analyses of stiffened plate/shell structures using the quadrilateral element SQ4C

In the present study, a novel quadrilateral element, namely SQ4C, combined with the Timoshenko beam element is proposed for the static and buckling analyses of stiffened plate/shell structures. The idea behind these elements is a treatment for shear locking as well as membrane locking arising from the framework of the first-order shear deformation theory and a mesh with curved shell geometry. Formulations with eccentricity are also presented in this paper for the general case. The static and buckling analysis solutions and comparison with other available numerical solutions are presented to illustrate the robustness of the proposed elements to stiffened plate/shell structures. This paper also helps engineers in supplementing their knowledge.
