Abstract
Study of the structural model of a solid body with an elementary volume in the form of a polyhedron using finite element analysis in the LIRA-SAPR 2017 software package
Incoming article date: 03.01.2022The paper considers a structural model of a solid body. Yu. N. Malashkin proposed a structural model of concrete, the main idea of which is an elementary volume in the form of a polyhedron formed from rod octahedra. When developing the model, only its analytical analysis was carried out. In this work, in the development of the model, its finite element analysis was carried out in the LIRA-SAPR software package. The study showed the coincidence of the qualitative and quantitative parameters of the model obtained by numerical and analytical calculations, confirmed its adequacy in relation to concrete.
