The Si-Ti-C-O fiber bonded ceramic material was creep-tested under three-point bend loading at 1 673 K, where deflection was measured at the loading point by means of the laser beam type extensometer. Furthermore, creep process was analyzed by using the proposed convenient analytical method and FEM. The creep constitutive equation was successfully determined through an inverse analysis using FEM ; parameters included in the equation were settled so that the calculated deflection-test time curve might coincide with the measured one. The calculation exhibited that compressive creep hardly occurred in this material. The convenient analysis method was useful for setting the initial values of the parameters in the FEM calculation.
