Analysis of deformation process characteristics in amorphous-crystalline polymers

In the framework of a two-component medium, the phenomenological approach is used to develop a system of constitutive equations describing the thermomechanical behavior of amorphous-crystalline polymers. This model is designed to describe the stress-strain states in the temperature range comprising the intervals of phase and relaxation transitions. The results of numerical experiments demonstrating the possibility of describing the characteristic properties of deformation processes typical of amorphous-crystalline polymers are given.
