Concrete is a heterogeneity material consisting of mortar and aggregate on meso level. Evaluation of fracture process in the meso level is useful to clarify the material characteristic of concrete. However, the mechanical characteristic in the meso level have not been fully understood yet. In this study, three-dimensional analyses of compression and tension test of mortar and compression test of concrete model are carried out by Rigid Body Spring Model (RBSM). In the analyses, fracture process and failure pattern of mortar and the effect of the existence of aggregate in concrete can be simulated qualitatively. These results show the possibility of 3D RBSM analysis to predict the concrete behavior quantitatively in various cases in the future.
