| Abstract | ||
|
A novel boundary stress resolution method is suggested in this paper, which is based upon the displacements of finite element analysis and of high precision with stress boundary condition strictly satisfied. The method is used to modify the Zienkiewicz-Zhu (Z(2)) a posteriori error estimator and for the h-version adaptive finite element analysis of crack problems. Successful results are obtained. | ||
