On a Conventional Stress Intensity Factor Calculation Technique of Surface Cracks
This paper describes one conventional stress intensity factor calculation procedure of surface cracks by Boundary Integral Equation Method. Using both stress and displacement type singular elements, the procedure utilizes displacement and traction solutions to give accurate stress intensity factor in the analysis with coarse mesh data. The numerical results show that the present approach improves the stability of tractions near crack tip and gives accurate stress intensity factor solutions in a sense of engineering evaluation.
