Finite Element Analysis of Shells of Revolution Using Triangular Discretization Elements with Corrective Lagrange Multipliers / Yu. V. Klochkov, A. P. Nikolaev, and O. V. Vakhnina. // Vestnik Moskovskogo Universiteta. Seriya 1. Matematika. Mekhanika. 2016. № 5. P. 59-63 [Moscow Univ. Mech. Bulletin. Vol. 72, N 2, 2017. P. 114-117].

A thin shell algorithm based on a special triangular finite element is described. The column of nodal variable parameters of this element additionally contains corrective Lagrange multipliers, which allows one to improve the conditions of compatibility between the elements in the framework of the variational formulation of the problem.

Key words: shell of revolution, finite element method, triangular finite element, Lagrange multipliers.
