Transport processes in bodies with a large number of cracks
Abstract
The treatment of cracks as a limiting case of inclusions involves two characteristic features. First, because of their small volume ratio, cracks can influence the effective conductivity only if their intrinsic relative conductivity is either large or small. Second, contrary to inclusions, where small strains generated by mechanical loads have almost no influence on the effective conductivity, cracks can strongly influence the effective conductivity, due to changes in their flare angle. These characteristics are analyzed for the case of noninteracting cracks. An attempt is made to extend the results to the case of interacting cracks.
