THREE-DIMENSIONAL NETWORK MODEL AND IT''''S APPLICATION
三维链网模型及其应用

Based on interaction between particles, the strain energy of materials is distributed according to the orientation of the line between particles, and three-dimensional network model of materials is proposed. The discretization in numerical computation is optimized, and the optimum solid angle is derived. The geometrical and physical parameters of the network model are calibrated. The network model is compared with typical finite element model. Taking a short-fiber reinforced composite as an example, the accuracy and capacity of the three-dimensional network are evaluated through a comparison with the shear-lag theory.
