Domain decomposition for linear elasticity with DG jumps and mortars

In this article, we present a domain decomposition method for solving a linear elasticity system. Data are transmitted by jumps, as in a discontinuous Galerkin method, and mortars are introduced at the interfaces to dissociate the computation between neighboring subdomains. A decoupling algorithm condenses the unknowns on the interface. The matrix of the system is constructed by parallel computation. Numerical experiments confirming the theory are presented.
