【 摘 要 】

The effective properties, elastic and conductive, of a polycrystalline material with intergranular cracks are considered. The specifics of intergranular cracking are that crack locations are restricted to intergranular boundaries. This necessitates re-examination of the usual homogenization schemes (where crack locations are unrestricted). The model developed here addresses this issue. (C) 2018 Elsevier Ltd.
