Locking free staggered DG method for the Biot system of poroelasticity on general polygonal meshes

Lina Zhao, Eric Chung, Eun-Jae Park

In this paper we propose and analyze a staggered discontinuous Galerkin method for a five-field formulation of the Biot system of poroelasticity on general polygonal meshes. Elasti…
