The analyses of the numerical methods of calculation of mechanics problems, based on the variation principle of Lagrange, such as the Finite Element Method (FEM) and the method of Moment Schema Finite Elements (MSFE), is given in the paper. The general formula to find the stiffness matrix of finite elements for MSFE is developed. The model of calculation of the energy functional of rectangular three-dimensional finite element, based on the variation of the problem statement, is developed.
Keywords: finite element method, method of moment schema finite elements, stiffness matrix, finite element.
