Abstract
A gradient-based adaptation procedure is proposed in this paper. The relative error in total strain energy from two adjacent adaptation stages is used as a stop-criterion. The refinement-coarsening is guided by the gradient of strain energy density. The procedure is then implemented in Element-Free Galerkin method. Numerical examples are presented to show the performance of the proposed procedure.
