With progress of the computer technology and numerical simulation method, the numerical simulation of the fracture process of concrete materials has become possible. In this paper, the numerical simulation models of the two types of samples were carried out with the SOLID65 concrete element based on the ANSYS software platform. According to the results, the non-linear characteristic of the concrete material exhibited in the loading process is reflected by the phenomenon that the slope of the later stage shows some reduction in the simulated load - loading point displacement curve. That is to say, the behavior of the appearance and development of cracks can be simulated with SOLID65 concrete element in ANSYS.
