摘要
在形状记忆合金(简称SMA)Brinson本构模型基础上推导并给出了伪弹性分段线性化本构模型,该模型参数多,计算不发散,节省计算资源。文中给出了该模型用于结构抗震的计算实例,计算结果显示了该SMA伪弹性分段线性化本构模型在结构被动控制中具有优良的性能。
Based on Brinson constitutive model of SMA(shape memory alloy), the pseudoelastic linear constitutive model of SMA is induced. The linear model of SMA defines some parameters and has good convergent performance. Compared with other complex nonlinear models, the linear model can save computing resource. Numerical Example shows the better performance of linear model in enhancing passive control of structures.
