Abstract: g>simple technique for finite element mesh refinement is presented. The technique is based on maximizing strain energy in the elements. The implementation of the technique in a general purpose program is facilitated by the fact that all calculations can be made at the element level. An element-by-element iterative algorithm combining Jacobi and Gauss-Seidel iteration is presented for the solution of equilibrium equations. The algorithm does not require formulation of the global stiffness matrix. Several numerical examples from two-dimensional elasticity are presented to show the effectiveness of the algorithms developed.
