It was suggested to define Rabotnov's function (damage function) from the differential equation of the first order for simulation of a pre-destruction stage in creep process. In this paper, the damage function is for the first time determined directly from a series of creep tests, independently of the formulated differential equation which, generally speaking, does not concord with the experimental data. A non-linear model of the creep process is suggested taking into consideration the rate increase stage, using an integral operator as Lebega's norm, and containing a damage function determined experimentally.
Keywords: creep, damage function, modeling, experiment, generalized model, integral operator, norm of Lebeg.
