The thermomechancial behaviors of shape memory alloy (SMA) actuators and their applications of the shape adaptive structure are investigated model is implemented to analyze the unique characteristics of SMA strip such as the pseudoelastic bahavior and shape memory effect. The incremental SMA constitutive equations are implemented in the user supplied subroutine UMAT by using ABAQUS finite element program. In this model of SMAs, the shape memory effect is rdstricted to one-way applications. Smart Composite Wing is fabricated using SMA actuator and FBG optical fiber sensor. The shape change of structure is caused by initially strained SMA actuator bonded on the surface of host structure when thermally activated.
