Concrete is a heterogeneity material consisting of mortar and aggregate at meso scale. Evaluation of fracture process in this scale is useful to clarify the material characteristics of concrete. The authors have conducted meso scale analysis of concrete over a past few years by Rigid Body Spring Model (RBSM). In this study, three-dimensional RBSM analysis of concrete under biaxial compression stress condition is carried out where the analysis simulates the crack in normal direction to plane of specimen, which cannot be presented by two-dimensional RBSM analysis. |
