Spectral Analysis of Relaxation Properties of Polymer Yarns with an Amorphous/Crystalline Structure

Spectral analysis of relaxation properties of polymer yarns is used to give a physical interpretation of systems analysis methods and computational prediction of nonlinear hereditary relaxation of yarns with an amorphous/crystalline structure in the zone of nondestructive mechanical action. Spectral modeling of the relaxation properties of polymer yarns is based on a generalized classical Maxwell model. The selected normalized relaxation function is interpreted as the integrated particle distribution with respect to a logarithmic relaxation time scale. Such a physical interpretation of the relaxation function is useful for comparative analysis of the relaxation properties of polymer yarns.
