В статті розглядається метод, який дає можливість визначати в’язкопружну деформацію полімерного
матеріалу, в якому створюється складний напружено-деформований стан. Вирази для визначення деформацій
полімерного матеріалу можна використовувати для розрахунку дотичних і нормальних навантаження, які
мають забезпечуватися зусиллям, що створюватиме обладнання для переробки полімерних відходів, під дією яких
буде відбуватися руйнування полімерного матеріалу.
The article deals with the method that makes it possible to determine the viscoelastic deformation of a polymeric material in which a complex stress-strain state is created. Expressions for determining the deformations of a polymeric material can be used to calculate the tangential and normal loads to be provided by the effort that will create the equipment for the processing of polymeric waste, under the influence of which the destruction of the polymeric material will occur. In the first stage, the polymer waste is processed on the toothed rollers, where they are stretched and compressed; At the second stage, polymeric wastes with a relaxed structure are treated on devices with rolls of the Relo profile, where they undergo compression and shear deformations; in the third stage, the polymer waste with a partially destroyed structure is treated with a needle-cutter device where they are finally destroyed in the places that were most weakened in the previous stages. For determination of rational structural parameters of processing devices and technological modes of their work the processes of deformation of polymer material in these devices are considered. The specificity of polymers limits the use of resistance to materials to determine the strength and therefore it is necessary to make significant adjustments to them. The basis of the theory of strength and deformation of polymeric materials should be based on the lawfulness of the studies on the influence of the time, temperature, humidity, anisotropy and other factors.
