New constitutive relationship of shape memory alloy composite

摘要

Shape Memory Alloys (SMAs) have been a major element of Smart Materials and Structures. Many applications, however, call for the embedding of SMA materials within structure components to sense and/or control the thermo-mechanical response of the structures. Therefore, the works on developing constitutive relationship of SMA composite are needed. In this paper, a one-dimensional constitutive law of Shape Memory Alloy composite is developed based on Brinson's one-dimensional SMA constitutive relationship. The thermo-mechanical behaviors of SMA composite are simulated implementing this constitutive relationship. In addition, the bending of a bias SMA composite is also investigated.
