Abstract

Introduction: The virtual element method (VEM), introduced in [3] is designed for solving numerical problems de ned on arbitrarily shaped polygonal/polyhedral discretizations. Therefore, it will greatly alleviate the heavy burden placed on meshing complex CAD geometries when compared with the traditional nite element method. Furthermore, VEM could handle the non-conforming discretizations by allowing the existence of hanging nodes, which are treated as normal nodes in the element. The local h-re nement and p-version re nement could be easily implemented under the VEM framework. So far VEM has been successfully applied to solve various problems including topology optimization, contact, fracture, plate bending and vibration, inelasticity. In this work, we develop an arbitrary order virtual element method for the static bending analysis of Reissner-Mindlin plates. The transverse displacement and rotations are independently interpolated with the functions de ned in VEM spaces. The interpolation functions for transverse displacement are one degree higher than the functions for rotations. A benchmark problem is studied to verify the developed method. The optimal convergence rates for transverse displacement and rotations could be obtained from the numerical example.

Reissner-Mindlin板静弯曲分析的虚元法
[3]中介绍的虚元法(virtual element method, VEM)是为求解任意形状多边形/多面体离散化的数值问题而设计的。因此,与传统的有限元方法相比,它将大大减轻复杂CAD几何图形的网格划分负担。此外,VEM通过允许悬挂节点的存在来处理非一致性离散化,将悬挂节点视为单元中的正常节点。在VEM框架下,本地h-re元素和p-version元素可以很容易地实现。到目前为止,VEM已经成功地应用于解决各种问题,包括拓扑优化、接触、断裂、板的弯曲和振动、非弹性。在这项工作中,我们开发了一种用于Reissner-Mindlin板静态弯曲分析的任意阶虚元方法。横向位移和旋转分别与VEM空间中定义的函数独立插值。横向位移的插值函数比旋转的插值函数高1度。通过一个基准问题对所提出的方法进行了验证。通过算例可以得到横向位移和旋转的最优收敛速率。
