为了更好地控制驱动,人们希望在驱动方向上制造功能梯度形状记忆合金(FG-SMA)。这可以通过应用不同的热处理工艺来沿形状记忆合金圆柱体的半径产生梯度来实现。推导出了预测这种功能梯度形状记忆合金圆柱体宏观行为的解析解。用Tresa屈服准则和线性硬化来描述不同梯度参数下的不同相变。该模型算例的数值结果显示了与非梯度情形不同的伪弹性行为,以及变换的变分滞后环,提供了一种易于驱动控制的机制。当梯度消失时,模型可以退化到非梯度情况。
For better controllability in actuations, it is desirable to create Functionally Graded Shape Memory Alloys (FG-SMAs) in the actuation direction. It can be achieved by applying different heat treatment processes to create the gradient along the radius of a SMA cylinder. Analytical solutions are derived to predict the macroscopic behaviors of such a functionally graded SMA cylinder. The Tresca yield criterion and linear hardening are used to describe the different phase transformations with different gradient parameters. The numerical results for an example of the model exhibit different pseudo-elastic behaviors from the non-gradient case, as well as a variational hysteresis loop for the transformation, providing a mechanism for easy actuation control. When the gradient disappears, the model can degenerate to the non-gradient case.
