Abstract: | In cyclic loading in the W = const and 0 = const regimes, as in the 0 = const regime, both a low-temperature and a high-temperature thermal regime may exist, with an abrupt transition from the former to the latter. The effect of the loading regime on the temperature dependence of the hysteresis temperature rise T, which depends on the elastohysteresis properties of the material, results in the following relationship between the critical temperature rises: T0c![le](/content/r1472375500620p2/xxlarge8804.gif) TWc![le](/content/r1472375500620p2/xxlarge8804.gif) T c.Scientific-Research Institute of Plastics, Moscow.
