Numerical Integration of Some Arbitrary Functions over an Ellipsoid by Discretizing into Hexahedral Elements for Biomaterial Studies

International Journal of Chemical Engineering, Volume 2024, Issue 1, 2024.
This study mathematically examines chemical and biomaterial models by employing the finite element method. Unshaped biomaterials’ complex structures have been numerically analyzed using Gaussian quadrature rules. It has been analyzed for commercial benefits of chemical engineering and biomaterials as well as biorefinery fields.

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.

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.

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 ...

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.

A refined shear deformation theory for the analysis of laminated plates [PDF]

A refined, third-order plate theory that accounts for the transverse shear strains is presented, the Navier solutions are derived for certain simply supported cross-ply and antisymmetric angle-ply laminates, and finite-element models are developed for ...

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 ...

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.
