摘要: 在形状记忆合金丝增强复合材料中,形状记忆合金丝作为分布式驱动器使复合材料具有自适应功能.本文根据形状记忆合金的一维本构关系,对形状记忆合金丝增强复合材料的温度与应力、应变关系进行理论探索;对形状记忆合金丝增强复合材料的拉伸性能、温度变化时的自由回复和受限回复性能进行了实验,并与模拟计算结果进行了比较.Abstract: Composites reinforced with Shape Memory Alloy(SMA)wires employ the SMA wires as distributed actuators to achieve adaptive functions while in service.This paper presents at heoretical study on the thermo-mechanical characteristics of composites reinforced with SMA wires,based on the one-dimensional constitutive relation of SMA.Experimental results derived from tension,free recovery and rest rained recovery of composites reinforced with SMA wires are also presented and compared with the simulated results.
