Thermal effects are important in viscoelasticity in the same way that they are important in the special cases of classical elasticity and fluid dynamics. But in addition, in viscoelasticity theory there are really drastic temperature effects of a kind never considered in the classical theories. The mean relaxation time of a material depends very strongly on the temperature. Generally, the higher the temperature is, the quicker the material relaxes or complies. This kind of temperature-dependence is, of course, absent from the theories that involve no relaxation time.
