A new rate-dependent constitutive model of superelastic shape memory alloys and its simple application in a special truss moment frame simulation

Abstract

In this work, a new constitutive model of the behavior of shape-memory alloys is presented, based on earlier models, showing a very good agreement with the existing experimental results. A simple approximate application concerning the use of these alloys modelled as dissipation devices in a special truss-moment frame is demonstrated. The results obtained are considered sufficiently encouraging as a motivation for the ongoing work. © 2018 Maria I. Ntina and Dimitrios S. Sophianopoulos.
