摘要： 摘要：
基于复合材料层合壳理论，利用压磁压电纤维材料的本构关系，考虑在温度和电场、磁场作用下，推导含压磁压电材料的局部非对称分层子层壳的总势能及屈曲控制方程.分析子层屈曲时，考虑了面内横向位移.通过对不同铺层形式的计算，给出了温度、电场、磁场荷载作用下，压磁压电复合材料层壳的几何参数、物理参数对任意方向椭圆形的局部分层屈曲临界应变值的影响规律. 关键词：

Abstract: The local buckling near the surface of piezoelectric-magnetic laminated shells under electric, magnetic and thermal loads was investigated by energy methods. Based on the theory of composite laminated shell and considering the effects of electric, magnetic and thermal loads, the calculation formula of the total potential energy and the local buckling equation were derived by using the constitutive relationship. Here, the transverse displacement of sublaminated shell is considered to set up the local buckling models of the sub-laminated shell. The effects of temperature change, magnetic loading, electric loading and the parameters of geometry and physics on the local buckling critical strain were described and discussed.

Key words: piezoelectric-magnetic composites, laminated composite cylindrical shells, local delamination buckling, thermal loading, electric field, magnetic field; , critical strain
