根据混凝土试件三点弯曲试验的物理模型，用MFPA数值模拟软件分别对砂浆和混凝土的三点弯曲试件的破坏全过程进行模拟．给出两个试件的载荷与加载点位移关系曲线，并进行了对比分析．
According to the physical model of the three-point bending test of concrete specimens, the entire process of the three-point bending specimens of mortar and concrete was simulated using MFPA numerical simulation software. The curve of the load and load point displacement of the two specimens is given and compared.
