Abstract
An approximate analysis is used to obtain the stress intensity factors K for DCB specimens with a groove, loaded by splitting forces P. A review is given for the various approaches that have been taken to obtain the stress intensity factor for an ungrooved DCB specimen. The accuracy of the results is evaluated using the exact solution of K, which was finally obtained by Foote and Buchwald [1]. A so-called improved beam analysis is used to obtain K for a rectangular grooved DCB specimen. When the specimen is loaded by bending moments M, the solution of the stress intensity factor is given by Wu et al. [4].
