الوصف: | In the development of materials for structural purposes, the main focus is on the advantageous combination of mechanical and volume-mass properties. Due to the development of production, solid plates are increasingly being replaced by modern composite materials with improved properties, one of the varieties of which is layered composites with a honeycomb core. The most widespread are three-layer plates with solid face layers and a hexagonal honeycomb core. However, with the development of new technologies, including 3D printing, honeycombs with new geometries are gaining popularity, the mechanical properties of which make it possible to obtain layered composites with improved features. In this paper, three-layer plates with solid face layers and a tetrachiral honeycomb core are investigated. The influence of discretization (number of unit cells), relative density and thickness of the honeycomb core on the stress state of three-layer composites subjected to static bending under various boundary conditions is studied. Mathematical modeling is carried out within the framework of the theory of elasticity by the finite element method via three-dimensional modeling in the Comsol Multiphysics system, as well as using algorithms developed by the author for analyzing the stress state of multilayer plates with tetrachiral honeycombs by solving a plane problem of the theory of elasticity. As a result, good agreement is shown between the numerical results obtained using algorithms for solving a plane problem and via three-dimensional finite element modeling in the Comsol Multiphysics system, while the numerical results are qualitatively consistent with laboratory test data.
