用有限元法对粘弹基形状记忆合金 (SMA)复合材料层合板在横向均布载荷作用下的挠度进行了研究 ,结果发现 ,基体的热粘弹性对 SMA的作动性能有较大影响 ,且其程度随板边界的固结方式、SMA丝的数目、SMA的预应变、板的铺设角的不同而不同
The deflection of viscoelastic SMA (SMA) composite laminates under uniform transverse load was studied by finite element method. The results showed that the thermal viscoelasticity of the matrix had a great influence on the performance of SMA. And their extent varies with the mode of consolidation at the plate boundaries, the number of SMA wires, the pre-strain of the SMA, the lay angle of the plate
