Abstract

We analyze some basic aspects of micromechanics of solids with multiple holes and microcracks. Two groups of properties are addressed: 1. Stress concentrations and microfracturing patterns in 2-D isotropic elastic solids with interacting elliptical holes. We examine various physical effects produced by interactions and the impact of hole eccentricities on these effects. Patterns of stress concentrations in such mixtures imply certain microfracturing patterns in materials with multiple defects. 2. Effective elastic properties of the isotropic and orthotropic solids with arbitrarily (randomly or non-randomly) oriented holes of diverse shapes. We describe the potential-based p
