An adaptive finite element mesh generation algorithm for microstructure of composite materials

摘要: According to the feature of particulate composite microstructure, an adaptive finite element mesh generation algorithm was developed for multi-particle packing structure. Based on force equilibrium method, compared a truss structure with inner force; distances between nodes particles, particles and curvature were adopted build size function. The summation calculated by function force-length Then, location updated iteration until equilibrium, formed. At last, meshes two microstructures different type given. result shows captures geometrical mechanical well, is simple efficient perform.
