Abstract
In this research, the thermomechanical responses of shape memory alloy(SMA) actuators and their applications in the structures combining strip SMA actuators are investigated. The numerical algorithm of the 3-D SMA thermomechanical constitutive equations based on Lagoudas model is developed using user material(UMAT) subroutine written by FORTRAN. For the numerical results, the ABAQUS finite element program has been utilized with UMAT subroutine of the numerical algorithm of SMAs. The interactions between the host structure and SMA strip actuator are numerically investigated.
