In this paper we describe our implementation of the edge-based smoothed finite element method (ES-FEM) for physically and geometrically nonlinear problems in the finite element software Code Aster. The implementation works for linear triangular elements. We apply our implementation to linear and geometrically and materially nonlinear problems. We compare the simulation results obtained by this method with those obtained with standard FEM using linear triangular and quadrilateral elements. The results show that the accuracy of the solutions achieved with ES-FEM using linear triangular elements are comparable with those of standard FEM using quadrilateral elements. ES-FEM is especially very useful regarding large deformation problems because it has the ability to work with largely distorted meshes and naturally avoids shear locking. These facts lead to a high computational efficiency and low computational costs.
