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