Experimental identification of thermomechanical model for glass polymers

The phenomenological model of thermomechanical behaviour of polymeric materials over the temperature range, including relaxation transition to a glassy state (glass transition) and inverse transferring (softening) is considered. Obvious interpretation of stress-strain state effects of a vitrifying material by the offered mechanical model tools is done. The system of experiments for identification of material functions and constants is formulated. Some tests for two types of vitrifying polymers – a calibration epoxy and PMMA are spent.
