tress concentrations and microfracturing patterns in a brittle-elastic solid with interacting pores of diverse shapes

Elastic interactions between holes of diverse eccentricities, as well as between holes and cracks, are analyzed. We examine physical effects produced by interactions and the impact of hole eccentricities on these effects. Mixtures of strongly interacting holes of diverse eccentricities and sizes are of particular interest. Patterns of stress concentrations in such mixtures imply certain microfracturing patterns in materials with multiple defects. C 1997 Elsevier Science Ltd.
