Abstract
Abstract. Currently very popular among engineers and scientists are the software systems, which are based on the finite element method (FEM).
The basic concept of the finite element method is a direct discretization of the calculated system that is divided by the calculated net into finite elements. In the paper are considered the questions of convergence of the finite element method for plate elements.
Based on the premises made is carried out the numerical calculation experiment of the stress-strained state of three-layer beams and compared the results with theoretical data obtained from the results of the calculation of three-layer beam (TB) by the method described in the Kobelev V.N reference book
