Finite Element Analysis of Functionally Graded Mindlin–Reissner Plates for Aircraft Tapered and Interpolated Wing Defluxion and Modal Analysis

Mathematics
This paper explores and discusses how wing structures vibrate by using the Mindlin–Reissner plate theory, which takes into consideration the effects of transverse shear deformation and rotary inertia.

A triangular element based on Reissner‐Mindlin plate theory

International Journal for Numerical Methods in Engineering, 1990
AbstractA new triangular plate bending element based on the Reissner‐Mindlin theory is developed through a mixed formulation emanating from the Hu‐Washizu variational principle. A main feature of the formulation is the use of a linear transverse shear interpolation scheme with discrete constraint conditions on the edges.

Finite element model based on refined plate theories for laminated glass units

Latin American Journal of Solids and Structures
Laminated glass units exhibit complex response as a result of different mechanical behavior and properties of glass and polymer foil. We aim to develop a finite element model for elastic laminated glass plates based on the refined plate theory by Mau ...

Existence theorems in the geometrically non-linear 6-parametric theory of elastic plates

, 2013
In this paper we show the existence of global minimizers for the geometrically exact, non-linear equations of elastic plates, in the framework of the general 6-parametric shell theory.

A simple triangular finite element model for analysing the linear static behaviour of thick sandwich plates with equivalent material properties

Advances in Civil and Architectural Engineering
This study presents a simple triangular finite element model for analysing the linear static behaviour of thick sandwich plates. What sets this work apart is its unique combination of the deformation approach with Airy’s function and analytic integration.

A low-order nonconforming finite element for Reissner-Mindlin plates [PDF]

, 2005
We propose a locking-free element for plate bending problems, based on the use of nonconforming piecewise linear functions for both rotations and deflections.

Shape differentiability of the eigenvalues of elliptic systems

, 2014
We consider second order elliptic systems of partial differential equations subject to Dirichlet and Neumann boundary conditions. We prove analyticity of the elementary symmetric functions of the eigenvalues, and compute Hadamard-type formulas for such ...

Free vibrations of laminated composite elliptic plates [PDF]

The free vibrations are studied of laminated anisotropic elliptic plates with clamped edges. The analytical formulation is based on a Mindlin-Reissner type plate theory with the effects of transverse shear deformation, rotary inertia, and bending ...

On the Justification of Plate Models [PDF]

, 2018
In this paper, we will consider the modelling of problems in linear elasticity on thin plates by the models of Kirchhoff-Love and Reissner-Mindlin. A fundamental investigation for the Kirchhoff plate goes back to Morgenstern (Arch. Ration. Mech. Anal.
