We expose an algorithm for calculating thin arbitrary shells on usig a triangular discretization element with correction Lagrange multipliers. The rigidity matrix of the triangular element is formed using the methods for approximating displacements as scalar and vector quantities.
Keywords: shell, triangular discretization element, scalar approximation, vector approximation.
Mots-clés : Lagrange multipliers
