The possibility of applying the methods of the theory of random processes in order to predict creep in polymer materials of the rheologically simple type under random transient stress is established. The transient random stress is simulated by a one-

Experimental attempts to confirm the applicability of time-temperature superposition as a means of predicting the deformation of polymeric materials are reviewed. Examples of the use of the method for the accelerated testing of amorphous and crystall

The class of rheologically simple polymeric materials is defined. A model, based on the use of the time—stress and time—temperature superposition principles, that permits a compact description of the thermocreep of polymeric materials with physic

As in the case of the selection of the simplified equations used in the theory of nonlinear viscoelasticity, variants of the equations of the temperature-time dependence of the strength of polymer materials are constructed on the basis of some simila

A variant of a statistical probability interpretation of elementary micromechanisms of formation of viscoelastic deformations of polymers is examined with the aid of the concept of dissymmetric media and the dissymmetry coefficient. A new rheological
