Two-Dimensional Statistical Micromechanical Models for Microcracked Brittle Solids

by K. H. Tseng, Princeton Univ, Princeton, United States,

Document Type: Proceeding Paper

Part of: Engineering Mechanics

Abstract:

Recent development undertaken by the authors in two-dimensional statistical micromechanical models for brittle solids with randomly located interacting microcracks is presented. Overall effective compliances of microcracked solids are at focus. Microcrack opening displacements for polynomial loadings are derived. Based on new, accurate, approximate solutions of two-microcrack interaction problem, improved effective compliances are constructed within the ensemble-volume average framework.
