摘要

Stress intensity factor determination plays a central role in linearly elastic fracture mechanics (LEFM) problems.Fracture propagation is controlled by stress field near the crack tip.Because the stress field near the crack tip is asymptotic dominant or singular,it is characterized by stress intensity factor.
