3-D Mesomechanical Analysis of Brittle Microcracking Solids and Improvement of Damage Mechanics Models : 2nd Report, Anisotropic Damage Mechanics Model

Abstract

The three-dimensional mesomechanical simulation method proposed in the first report of the present study has been applied to the analysis of a brittle microcracking solid under various loading conditions. The validity and the limitation of the existing anisotropic damage mechanics model have been studied by comparing its predictions with the results of mesoanalysis. Based on these results, the evolution equation for the microcrack density in the existing damage mechanics model has been improved. The validity of the improved damage mechanics model has been verified against the results of mesoanalysis.
