TL;DR: The reformulated four-node element has exhibited an excellent behaviour in static finite element analyses being free of shear and machine locking problems and of zero energy modes and modelling accurately relatively thick plates.

TL;DR: In this paper, the behavior of the C0 plate elements in modelling edge zone effects is analyzed by utilizing the classical and a recently proposed formulation Boundary layers are shown to develop under the activation of an edge zone moment redistribution mechanism.

TL;DR: In this article, an integrated physical model for closed thin-walled cylindrical shells under nonaxisymmetric pressure is proposed, based on the interaction of the beamplate bending, the membrane, and an equivalent ring foundation load-carrying mechanism, which is capable of capturing the overall physical behavior of the shell under both lower (n=0, 1) and higher load (n>1) harmonics.

TL;DR: In this paper, a new formulation was proposed for the removal of the shear and membrane locking mechanisms from the finite element equations of the structural C 0 shell, plate and beam elements.

TL;DR: In this paper, the behavior of a reformulated four-node Mindlin C 0 plate bending element in thin to very thin and in moderately thick element applications was analyzed and a simple technique was proposed to render the element completely locking-free.
