Effectiveness of the stress solutions in notch/crack tip regions by using extended boundary element method

In this paper, the extended boundary element method (XBEM) is employed to evaluate the singular stress fields of plane V-notched/cracked structures based on the linear elastic theory. Firstly, the V-notched/cracked structure is divided into two parts, which are a small region around the notch tip and the outer region without the tip region. Then, the expressions of the asymptotic series expansion of the singular stress fields in the notch tip...
