A triangular thin shell element for the linear analysis of stiffened composite structures

Original language is angielski.

A three node flat shell element with six engineering displacement degree-of-freedom at each node is developed. The basic formulation allows for the arbitrary location of the reference surface in which the membrane forces and bending moments are fully coupled. The well-known, highly accurate, DKT bending element is combined with a higher order membrane element in order to obtain...
