Shape　memory　polymers　(SMPs)　are　a　class　of　intelligent　materials,　which　are　defined　by　their　capacity　to　store　a　temporary　shape　and　recover　an　original　shape.　In　this　work,　the　shape　memory　effect　of　SMP　deployable　hinged　shell　is　simulated　by　using　compiled　user　defined　material　subroutine　(UMAT)　subroutine　of　ABAQUS.　Variations　of　bending　moment　and　strain　energy　of　the　hinged　shells　with　different　temperatures　and　structural　parameters　in　the　loading　process　are　given.　The　effects　of　the　parameters　and　temperature　on　the　nonlinear　deformation　process　are　emphasized.　The　entire　thermodynamic　cycle　of　SMP　deployable　hinged　shell　includes　loading　at　high　temperature,　load　carrying　with　cooling,　unloading　at　low　temperature　and　recovering　the　original　shape　with　heating.　The　results　show　that　the　complicated　thermomechanical　deformation　and　shape　memory　effect　of　SMP　deployable　hinge　are　influenced　by　the　structural　parameters　and　temperature.　The　design　ability　of　SMP　smart　hinged　structures　in　practical　application　is　prospected.
