Abstract
Problem Statement (Relevance). In order to reduce the cost of products made of metal-like, variatropic mineral and convergent composites, dispersive components are sought to be produced selectively when processing elastic-viscous-plastic material waste. In particular, in accordance with the requirements for the products, such wastes are crushed into secondary granules, chips or fibers by cutting, providing the required geometry without disturbing the structure and physical and mechanical properties of the substance. If to study the structure, for example, of fibrous media of a natural origin, it is enough to apply a microscope, their physical and mechanical properties, as a rule, are determined only empirically, and the values of their parameters can vary significantly depending on the natural features of their formation. Such parameters are the basis not only for the development of the production and technical base, but also for scientific research. Objectives. For clarity, it is more expedient to measure stresses and deformations in elastic-viscous-plastic media by applying the polarization optical method, using equivalent optically sensitive materials. Methods Applied. The article is devoted to the selection of sample formulations from equivalent materials, taking into account similarity coefficients for a model assessment of the stress and strain state of various types of leather at the penetration of a simulator of a double blade tool, namely a disperser. Result. The article describes the methodology of the model experiment, assesses strength and force characteristics of the penetration process, and provides visual images of the resulting stresses in equivalent transparent, optically sensitive materials. The obtained results can be useful for researchers and material scientists in the development of nature-like composites, for designers, developing new methods and devices for selective grinding of elastic-viscous-plastic material waste, as well as for waste recyclers.
Keywords
