Time — Moisture superposition

The results of creep tests on PN-3 polyester resin are given for various values of the temperature and moisture content of the material. It is shown that moisture content and time, like temperature and time, have an interchangeable effect on creep; i.e., in addition to a time-temperature (T-t) there is also a time-moisture (w-t) analogy. The (w-t) analogy can be used to predict the long-time creep from accelerated test data.

Time-stress superposition in nonlinear viscoelasticity

Using low-density polyethylene, whose viscoelastic properties are nonlinear at high stresses, within reasonable limits of stress and time it is possible (under certain conditions) to use time-stress superposition, as well as time-temperature superposition, to predict the long-term creep of polymer materials. A variant of the compact approximation of nonlinear vicoelasticity effects in polymers is proposed.

Multiparametric prediction of the creep of polymer materials

AbstractThe article discusses phenomenological methods for predicting long-term creep, using stress-, temperature-, and vibro-time analogies. Starting from several previously introduced hypotheses, the article proposes a generalized nonlinear thermo-vibro-rheological relationship in which the complex stress-, temperature-, and vibro-time dependences are reduced separately to a time dependence (with certain basic reference values of
