Study of deformation dependence on time in polyethylene terephthalate for different static loads and irradiation doses

Abstract

Complex experiments were conducted on deformation dependence on time for different static loads and irradiation doses in polyethylene terephthalate. Curves of time (t) dependence of deformation (?) show a significant change in the behavior of the material after irradiation. The obtained dependence curves of on t for both non-irradiated and irradiated materials are satisfactorily described by cascade-probability model.
