摘　　要：通过对多层复合结构的力学分析 ,得出了复合结构体系的广义能量泛函 ;并针对具体的算例 。Composite structures take an important position in the rational type-selecting of explosive resistant structures. A composite structure has small sectional rigidity and produce large relative deformation under dynamic loading; at the same time, the material strength of the section could be brought into play, hence the dynamic loading capability of the structure is increased. This paper gives the generalized functional of energy of the composite structure system, and suggests the rational rigidity matching relationship of the structural section through a calculation example.
