Abstract
This paper is devoted to the development of a new geometrically nonlinear finite element for composite-material shell structures. Nonlinear analysis of composite-material shell structures using the finite element method and the search for a satisfactory finite element for shell structural nonlinear analysis has been active for decades. One main approach for formulating shell finite elements is to enhance a linear shell element to perform nonlinear analysis by adding an appropriate geometric stiffness matrix and implementing a full Newton-Raphson procedure to the linear analysis computer program (Argyris et al. [1], Mohan and Kapania [2]). The presented finite element is, in a broad view, a part of this approach.
