An h-adaptive boundary element method for fracture mechanics

研究成果: Conference contribution

摘要

This paperAEs aim is to modified the sample point error analysis method proposed by Kawaguchi and Kamiya, and to develop an h-adaptive quadratic boundary element mesh refinement procedure to be implemented into linear elastic crack problems. Two sample pointed are selected in each of the quadratic boundary element, and the extended error indicators at the sample points are calculated. The h-refinement procedure is based on the average extended error for all of the boundary elements. The stress intensity factors at the crack tip are calculated by the displacement extrapolation method and the J-integral calculation at the end of each iteration. The results show that the use of singular element at the crack is less important if the J integral method is to be used to find the SIF, because the J integral method gives the best result with fewer iterations.
