Research on Mesoscopic Modeling Method of Composites Based on Particle Repulsion

Abstract:
According to the electromagnetic and structural mesoscopic finite element method (FEM), the method of generating mesoscopic geometry model based on particles repulsion is formed with calculation of vector introduced to deal with position and displacement of particles. Focusing on the configuration composed by particles without overlap, the models are generated by the algorithm, while the particle initial proportion and particle sizes are maintained. The interface program between the algorithm and the typical FEM software also developed to improve the practicability of the method. It is shown that this method, the three-dimensional mesoscopic geometry model and the FEM model of complex composites can be generated automatically.
