Abstract: The microelement method, which establishes the immediate relation between the microstructure of material and dynamic character of structural member in composite material, is discussed. The method, firstly, divides the composite structural member into a set of macroelements, then analyzes the microstructure, and translates the variables of the microstructure into variables of nodes for calculation. In this method, any arbitrary pattern of microstructure and any tiny change will be reflected in macrocharacter without increasing the degrees of freedom.
Keywords: Microelement, composite material, dynamic character.
