Abstract: | Summary An estimation is found for the energy release due to fragmentation of a brittle inhomogeneity of ellipsoidal shape embedded
in a ductile matrix under remote static loading. In the state of completed fragmentation the inhomogeneity is replaced by
a void with zero stiffness. Thus, the problem of estimating the energy release reduces to the eigenstrain problem solved by
Eshelby. The energy release calculated for prolate spheroidal inhomogeneities is used in the balance of energy to determine
the crack density. The application to the geological system of garnet inhomogeneities embedded in a quartz matrix is considered. |
