**Abstract**
 An analytical formulation is presented which has been developed and validated for use in calculating the stress intensity factor due to water-ice inclusion in both transversely ISOTROPIC and ORTHOTROPIC matrices. By use of finite element analysis, it was established that the stress field in the vicinity of an elliptical inclusion was an acceptable analytical idealisation by which to obtain the stress intensity for a crack with ice inclusion. Results are discussed which indicate that the stress state in a slender elliptic elastic inclusion can be used to approximate the stress field at the crack face, which could subsequently be adopted to determine the stress intensity factor. Analyses of the delamination and fatigue life prediction for freeze-thaw cycling are provided as specific applications of the model. 13 refs.
