Since the mid-1960s when the forms of curved shell finite elements were originated,
including those pioneered by Professor Gallagher, the published literature on the subject …

In this paper, mixed finite element (MFEM) equations which are based on a functional are
obtained by using the Gâteaux differential (GD) for laminated composite beams. Higher …

The main objective of the present work is to give the systematic way for derivation of
Kirchhoff plate‐elastic foundation interaction by mixed‐type formulation using the Gâteaux …

In mixed finite element formulation three different methods:(1) Hellinger-Reissner principle
(HR);(2) Hu–Washizu principle (HW);(3) Gâteaux Differential Method (GDM), are widely …

Static analysis of stiffened shells has been carried out using an eight-noded isoparametric
element for the shell and a three-noded curved beam element for the stiffener. A same …

This study presents a mixed finite element formulation for the stress analysis of laminated
composite beams based on the refined zigzag theory. The Hellinger–Reissner variational …

In this study, circular beams with variable cross-sections on elastic foundations under
arbitrary loading are analyzed by the finite element method. The Winkler hypothesis is …

In the present study, a novel quadrilateral element, namely SQ4C, combined with the
Timoshenko beam element is proposed for the static and buckling analyses of stiffened …

A new functional has been constructed for Reissner plates on Winkler foundations through a
systematic procedure based on the Gâteaux differential. In this functional there exists eight …

An isoparametric rectangular mixed finite element is developed for the analysis of hypars.
The theory of shallow thin hyperbolic paraboloid shells is based on Kirchhoff–Love's …
