Abstract
A flat triangular finite element is proposed for thin shells, in which the approximations of membrane and bending deformations are implemented with help of the limit tractability of finite element analysis. Increasing the degree of coincidence between the rotation angles of finite elements is achieved with the penalty functions. The high accuracy of this discretization scheme is illustrated on the samples of cylindrical panel and shell in the form of a hypar.
