摘　　要：智能材料具有自监测、自控制和自修复等一系列"智能"功能，近年来得到了飞速的发展。尤其在航空航天工业中展示了广阔的前景。主要分析内部嵌有压电材料的复合材料智能板。首先给出智能材料的本构方程，接着分析了智能板的平衡方程，并对其有限元的建模技术进行了讨论。最后列举了复合材料智能板的具体应用。There is function about survey, control and restore by itself in Smart material & intelligent structure . Re- cenily this material & structure is progress at very fast speed, especially in aeronautics and astronautics In this paper we analysis intelligent plate of composite material with piezoelectric element. At first the constitutive equation is educed, and than equilibrium equation of intelligent plate. The modeling technology of FEM is discussed. In the end it is appied for in an intelligent Plate of composite material, for example.
