Stress analysis of star cracks

This paper deals with the elastic problem about starcracks using the technique of conformal mapping with complex variablefunction method. The analytic solutions of the stress intensity factors areobtained for mode I and mode II problems at the crack tip. The present modelcan be used to simulate the well-known Griffith cracks, the three straightcracks with common point and uniform distribution, the cross crack andtheeight symmetry straight cracks.
