Triangular Six-Node Finite Element with 36 Degrees-of-Freedom

The article is concerned with problem of forming six-nodes triangular plate finite element with drilling rotation degrees of freedom. Stiffness matrix is formed by adding drilling rotation connectors and corresponding fictitious coefficients to the triangular six-nodes shell finite element of mixed type with 30 degrees of freedom. Element may be used for shell analysis of arbitrary geometry and structure including multilayered ones. Some results for cylindrical shells are presented.
