Variational determination of the crack trajectory in inhomogeneous media

Abstract:
Propagation of a crack through inhomogeneous media is considered in the variational formulation, whereby the path corresponding to the extremum of energy release during fracture is sought. A non-linear differential equation is obtained for the crack trajectory in an inhomogeneous medium subjected to specified tensile loading. A linearized form of this equation is investigated in order to characterise the crack propagation in media with different effective characteristics.
