摘要： 将伪弹性形状记忆合金（SMA）纤维镶嵌在复合材料层合结构的顶层和底层，联合采用经典层合梁理论和有限元法，在考虑SMA的相变特性和材料非线性与层合结构变形相互耦合的基础上，建立了SMA混杂复合材料层合结构的静力学模型，利用MATLAB软件模拟了该复合材料层合结构在横向和纵向加卸载过程中的静力学响应，研究了其耗能能力和耗能机理。研究发现，SMA混杂复合材料层合结构加卸载过程中的载荷变形量曲线形成了封闭的滞后环，这表明内嵌SMA纤维的复合材料层合结构具有伪弹耗能能力。

Abstract: Pseudoelasticshape memory alloy (SMA) fibers are embedded in the top layer and the bottom layer of a composite laminated structure. The statics model of the SMA hybrid composite laminated structure was established by combining using the classical laminated beam theory and the finite element method.The coupling between the phase transformation, material nonlinearity of SMA and the deformation of the laminated structure was considered. The statics response of the SMA hybrid composite laminated structure was simulated by MATLAB during the transverse and longitudinal loading and unloading process. The energy dissipation capability and mechanism of the SMA hybrid composite laminated structure was studied. It was found that the loaddeformation curve of the SMA hybrid composite laminated structure during loading and unloading forms a closed hysteresis loop.This indicates that the composite laminated structure with embedded SMA fibers has the capability of pseudoelastic energy dissipation.
