ON THE ELASTIC COMPLIANCE OF A CIRCULAR HOLE WITH TWO SYMMETRIC RADIAL CRACKS INITIATED AT ITS BOUNDARY

摘要

A circular hole with two symmetric rectilinear radial cracks initiated at its boundary is analyzed from the point of view of its elastic compliance (contribution to the overall elastic properties of a representative volume). Results are obtained using Rice's connection between stress intensity factor and effect of a crack on the elastic properties of a material. We compare our result with that for a combine contribution of non-interacting circular pore and a rectilinear crack to show when this combination can be used for approximation of the elastic compliance contribution.
