Mechanical, appropriate mathematical models and their study of the stress-strain state of the elastic round in terms of elastomeric cushion for tractor engines will be developed. It is planned to continue the study of the fracture mechanics of piezoelectric bimaterials with interfacial cracks, which have mixed electromagnetic conditions on the shores and some other features. Mechanical and corresponding mathematical models of mechanics of fracture of electroelastic materials with between phase cracks and various electromagnetic conditions on their shores will be considered. The plan also includes physical and mathematical modeling of the processes of structure formation in metallic materials. According to the results of the research, reports will be made at international scientific conferences, articles will be published in the conference proceedings of professional publications and publications that are part of international scientific databases. The research will use developed and improved mechanical models and relevant mathematical models, the study of which is based on: general theorems, hypotheses and models of physics, materials science, mechanics of solid deformable body, theory of solving ordinary and partial derivatives of differential equations, developed and improved nonclassical methods of mathematical physics. Keywords: Rods, mechanical, mathematical, models, piezoelectric bimaterials, asymptotic methods popup.description2 Research is aimed at developing new and improving existing mechanical and mathematical models of structural elements and parts of industrial and agricultural machines under the action of static and dynamic loads. Based on the results of research, analogies in mechanical and mathematical models of problems of statics and dynamics of elastic elements of structures under the action of a moving inertial load have been substantiated, the method of mathematical physics has been generalized for problems of this class, which allows determining the initial values ​​of frequencies and critical values ​​of load movement speeds. The task of improving the design of the screw feeder of the disperser designed for grinding grain material has been solved. Existing industrial and agricultural facilities were analyzed in order to improve the technical characteristics, reliability and durability of load-bearing metal structures under static and dynamic non-stationary loads, namely, a trailed wide-grip seeding complex and an arched sectional hangar used for warehouses and production facilities. The urgent task of designing a rocker arm gripper scheme without redundant connections, energy rational and without dynamic overloads and with high efficiency has been solved. Taking into account finite deformations, the mechanics of the destruction of piezoelectric nanomaterials and the process of formation of interphase cracks in them, which have mixed electromagnetic conditions on the shores, were investigated. Physico-mathematical modeling of the processes of structure formation in metallic materials, atomic self-organization during paired growth of crystals was carried out. The development and improvement of mechanical models and corresponding mathematical models is based on general theorems, hypotheses and models of physics, materials science, mechanics of a rigid deformable body, the theory of solving ordinary and partial differential differential equations, as well as non-classical method Product Description popup.authors Huridova Viktoriia O.
