| 摘 要： | 从压电材料的非线性本构关系出发,应用Hamilton原理推导含有压电材料复合材料结构的变分方程,并证明对于具有二次本构关系的压电材料可以直接由二次本构关系得到其变分方程,推导出含有二次本构关系压电材料的复合材料结构的有限元动力方程,并提出利用压电材料的非线性进行复合材料结构振动控制的一种新方法.

| Abstract: | Based upon nonlinear constitutive relations of piezoelectric materials,the variational equations of composite material structures with nonlinear piezoelectric materials are derived by Hamilton's principle.Variation equations of piezoelectric structures with quadratic constitutive relations are proved quadratic constitutive relations can directly derive that.Finite element equations of composite material structures with nonlinear piezoelectric materials are derived.A new method is proposed to control vibration of composite material structures by nonlinear piezoelectric materials. |
