On the basis of an algorithm of time steps, a method to simulate the creep is developed for rib-reinforced composite media made of nonlinear hereditary phase materials whose behavior is described by the Rabotnov theory. The technique proposed allows one, at discrete moments of time, to consider such a composition as nonlinear elastic with the initial stress state. The use of an iterative process of the type of the method of variable elasticity parameters allowed us to linearize the governing relationships and to reduce the problem of calculation of creep of the composite media at discrete points in time to a series of linear elastic problems of the mechanics of composites.
