Shape　memory　polymers　(SMPs)　are　a　class　of　intelligent　materials　with　the　ability　to　recover　their　initial　shape　from　a　temporarily　fixable　state　when　subjected　to　external　stimuli.　In　this　work,　the　thermo-mechanical　behavior　of　a　deployable　SMP-based　hinged　structure　is　modeled　by　the　finite　element　method　using　a　3D　constitutive　model　with　shape　memory　effect.　The　influences　of　hinge　structure　parameters　on　the　nonlinear　loading　process　are　investigated.　The　total　shape　memory　of　the　processes　the　hinged　structure　goes　through,　including　loading　at　high　temperature,　decreasing　temperature　with　load　carrying,　unloading　at　low　temperature　and　recovering　the　initial　shape　with　increasing　temperature,　are　illustrated.　Numerical　results　show　that　the　present　constitutive　theory　and　the　finite　element　method　can　effectively　predict　the　complicated　thermo-mechanical　deformation　behavior　and　shape　memory　effect　of　SMP-based　hinged　shell　structures.
