| Abstract: | Non-convergence and pseudo-convergence are described in this paper for the h-adaptive finite element analysis of stress singularity problems with theoretical explanation given. A method is suggested, which can avoid the failure of h-adaptive finite element analysis and keep certain precision ofstresses. Numerical examples show that the method is suitable for the adptive analysis of engineeringproblems. |
