线弹性力学问题的杂交虚元法

Hybridization of the Virtual Element Method for linear elasticity problems

Franco Dassi, Carlo Lovadina, Michele Visinoni

摘要:

本文将[Arnold,Brezzi,1985,ESAIM:M2 AN]中提出的杂交方法推广到基于Hellinger-Reissner原理的线弹性问题的虚元法。为了说明这种技术,我们专注于2D的情况下,但其他方法和3D问题也可以考虑。我们还展示了如何设计一个更好的近似位移场使用一个简单的后处理过程。数值实验证实了二维和三维问题的理论。

英文摘要:

We extend the hybridization procedure proposed in [Arnold, Brezzi, 1985, ESAIM: M2AN] to the Virtual Element Method for linear elasticity problems based on the Hellinger-Reissner principle. To illustrate such a technique, we focus on the 2D case, but other methods and 3D problems can be considered as well. We also show how to design a better approximation of the displacement field using a straightforward post-processing procedure. The numerical experiments confirm the theory for both two and three-dimensional problems.
