  • 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.
