Abstrakt		The mechanical properties of polymeric materials quite generally depend on time, i.e., on whether they are deformed rapidly or slowly. The time dependence is often remarkably large. The complete description of the mechanical properties of a polymeric material commonly requires that they be traced through 10, 15, or even 20 decades of time. The class of polymeric materials referred to as thermorheologically and/or piezorheologically simple materials allows use of the superposition of the effects of time and temperature and/or time and pressure in such materials as a convenient means for extending the experimental time scale. This paper presents a critical review of models proposed to describe the effect of temperature and/or pressure on time-dependent thermorheologically and/or piezorheologically simple polymeric materials. The emphasis here is on the theoretical aspects, although experimental results are used as illustrations wherever appropriate.
