Three-Dimensional Elastic Stress Analysis in Materials With Many Inhomogeneities.

Abstract

The research effort was concentrated on micromechanics of brittle materials with multiple interacting defects, and on the impact of the defects on the overall (effective) properties. The work addressed the following problems: (1) Three-dimensional mechanics of crack interactions. (2) Three-dimensional mechanics of crack-microcrack interactions. (3) Relationship between fracturing of a brittle microcracking material and reduction of its effective stiffness. (4) Effective elastic properties of cracked solids and continuum characterization of crack arrays. (5) Mechanics of solids filled with compressible fluid. (6) Anisotropic materials with interacting cracks..... Brittle materials, Crack interactions, Microcrack interactions, Brittle fracturing, Cracked solids, Anisotropic materials, Micromechanics.
