Calculation of rotation shells using finite triangular elements with Lagrange multipliers in variative approximation of displacements

Аннотация

In calculations of the hard deformed state of rotation shells, the problem of incompatibility of triangular sampling elements with respect to derivatives of components of displacement vectors arises. In order to eliminate this weak point, it is proposed to adjust Lagrange multipliers in combination with an invariant vector procedure of approximation of displacement fields.
