A dual-mixed finite element method for nonlinear incompressible elasticity with mixed boundary conditions

Gatica, Gabriel N.; Gatica, Luis F.; Stephan, Ernst (2007)

In this paper we consider the Hu-Washizu principle and propose a new dual-mixed finite element method for nonlinear incompressible plane elasticity with mixed boundary conditions. The approach extends a related previous ...
A FEM–DtN formulation for a non-linear exterior problem in incompressible elasticity

Gatica, Gabriel; Gatica, Luis; Stephan, Ernst (2003)

In this paper, we combine the usual infinite element method with a Dirichlet-to-Neumann (DtN) mapping, derived in terms of an infinite Fourier series, to study the solvability and Galerkin approximations of an exterior ...
