This paper deals with a study to determine a compliance model of flexure hinge considering creep subjected to pure applied moment. The work can be considered an extension of previous investigations on typical notched flexure hinge. Analytical equations are derived using Castigliano's second theorem and creep power-law that the creep constitutive equation and parameters is obtained from the standard uniaxial tensile creep experiments. The compliance considering creep is simulated using the finite element (FE) method and results show a maximum error of 1.27% between the theoretical value and simulation result, thus verifying the accuracy of our analytical compliance model. The proposed compliance model is able to predict the creep behaviour of the flexure hinge using on flexure mechanism under the space high temperature environment.
