Development of Driving Force Constitutive Model of Shape Memory Alloy Based on OpenSees

Shape memory alloy is a type of intelligent material for civil engineering. Based on its driving force test data, the driving force constitutive model was proposed. Based on OpenSees platform, the shape memory alloy materials were added to the material library to comprehensively reflect the influence of initial stress, pre-strain, temperature and other factors on driving force. The OpenSees calculation results were compared with the driving force experimental data. The results show that they are in good agreement, providing a realization path for driving force simulation analysis based on OpenSees platform.
