Stress intensity factor of a penny-shaped crack with small-disturbed crack front line

In this paper, the stress intensity factor K for the crack front line α − ε (1 + cosmθ ) , which is slightly perturbed from a complete circular line with a radius of α, is solved. The mathematical procedure chosen in this study is based upon the perturbation technique developed by Rice for solving...
