| Abstract: | in this paper, a H-version finite element scheme for 2-D analysis is presented. Two error indicators are adopted in mesh refinement of H-version to increase the accuracy of FE results for the stress concentration area. The stress disperse degree is used to estimate the global error of the finite element solution. Two examples are given to verify the validity of the H-version FEM presented here. |
