复合材料夹层板动态特性的有限元分析

Finite Element Analysis for Dynamic Characteristics of Composite Sandwich Plates

采用考虑复合材料叠层板一阶剪切变形的位移模式，推导了复合材料夹层板自由振动的有限元公式，并提出了处理阻尼问题的方法。数值结果与实验的对比表明，这一方法是合理而有效的。

Using a shear deformation model which includes shear deformation of composite face plates,finite element equations for composite sandwich plates are derived.A method is advanced for dealing with damping problem.By contrasting the numerical result with the experimental one,the method is proved to be reasonable and effective.
