Circumferentially cracked hollow cylinder under thermal shock - Revisited

The axisymmetric problem of a circumferentially cracked transversely isotropic hollow cylinder under thermal shock is considered. It is demonstrated that appropriately normalized stress intensity factors (SIFs) depend only on three material parameters and the transient temperature distribution. It is also found that only one of these parameters has a significant effect on the normalized SIFs. Reduction in the number of material parameters, from seven to practically one, makes it possible to propose simple approximate expressions for the calculation of normalized SIFs in terms of geometric parameters. Both inner and outer surface cracks are addressed. Approximate expressions giving SIFs are presented.
