Viscoelastic-Plastic and Elastic Components of Mechanical Work of Deformation of Polymer Textile Materials

Deformation in polymer materials can be /tentatively divided into three components: elastic, viscoelastic, and plastic. Division of full deformation into components is a difficult task because of their simultaneous occurrence and further development. Only by physically validated analytical description of the rheology of polymer materials in conjunction with measurements of various deformation processes can we get information about the complex pattern of distribution of particles of the material over relaxation and delay times.
