An arbitrary order locking-free weak Galerkin method for linear elasticity problems based on a reconstruction operator
Fuchang Huo, Ruishu Wang, Yanqiu Wang +1
The weak Galerkin (WG) finite element method has shown great potential in solving various type of partial differential equations. In this paper, we propose an arbitrary order locki…
