Tensile Test of Shape Memory Alloys and Numerical Simulation
Shape memory alloy (SMA) as an effective alternative to steel has received much attention.The constitutive model of SMA has raped developed for nearly 10 years,such as Boyd and Lagoudas model,Auricchio model,etc.However,a number of constitutive models were more complex,and not easily applied to engineering.In order to study SMA concrete pullout test using numerical simulation software,the tensile property of superelastic SMA was studied in this paper,different units (SOLID185 and LINK8) were simulated at the same time.Through the comparative analysis of results of different constitutive models,an easier used constitutive model of SMA was obtained.Combining with the numerical case,it shows that link8 is more convenient and accurate to simulates SMA.
