| Abstract: | For the further study of the meso-strueture of concrete, Matlab and Monte Carlo method were combined to automatically generate the concrete three-dimensional spherical aggregate model and use the finite element analysis software for grid division and check of the model. The simulation results show that the established model achieves the randomness of aggregate generation and the generated aggregate is con- tinuous. The method is simple and easy to use, and the model is visual, highly accurate, and conducive to further research of the macro and micro mechanical properties of concrete. |
