混凝土是细观尺度上由砂浆和骨料组成的非均质材料。在此尺度下评价断裂过程有助于阐明混凝土的材料特性。作者在过去的几年中，进行了细观分析混凝土的刚体弹簧模型（RBSM）。在这项研究中，三维RBSM分析混凝土在双轴压应力条件下进行的分析模拟裂纹在法线方向上的试样的平面，这不能由二维RBSM分析。
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.
