N2 - In recent years, it has been attempted to clarify the damage evolution in solid materials from irreversible thermodynamics. In this study, tensile tests were carried out polyimide and entropy generation amounts were calculated until failure based on irreversible thermodynamics. The parameters of viscoelastic/plastic model were determined by fitting with the result of creep and recovery tests. We predicted fracture of polyimide in the tensile test by using viscoelastic/plastic model which considered entropy generation amounts as criterion of damage.
