The Realization of Driving Force Constitutive Model of Shape Memory Alloy Based on OpenSees

Abstract

Abstract Based on the driving force test data of shape memory alloy (SMA), the constitutive model of SMA driving force is proposed, and the secondary development is carried out on the platform of OpenSees software. SMA material was added to OpenSees, and the results show that the calculation results in this paper are consistent with the experimental data. It provides a realization path for driving force finite element analysis using OpenSees platform.
