On mixed finite element methods for the Reissner-Mindlin plate model
Ricardo G. Durán,Elsa Liberman +1 more
TL;DR: In this article, the convergence of mixed finite element approximations to the Reissner-Mindlin plate problem is analyzed, and several known elements fall into the analysis, thus providing a unified approach.
Journal ArticleDOI
Error Estimates for Low-Order Isoparametric Quadrilateral Finite Elements for Plates
TL;DR: This paper considers two lowest-order methods of this family of elements called MITC (mixed interpolation of tensorial components) of Reissner--Mindlin equations based on quadrilateral meshes and obtains optimal H1 and L2 error estimates for both methods.
Journal ArticleDOI
Approximation of the vibration modes of a plate by Reissner-Mindlin equations
TL;DR: This paper deals with the approximation of the vibration modes of a plate modelled by the Reissner-Mindlin equations by applying a general approximation theory for spectral problems, and obtains optimal order error estimates for the eigenvectors and the Eigenvalues.
Journal ArticleDOI
A posteriori error estimator for a mixed finite element method for Reissner-Mindlin plate
TL;DR: An a posteriori error estimator for a mixed finite element method for the Reissner-Mindlin plate model is presented and it is shown that the estimator yields local lower and global upper bounds of the error in the numerical solution in a natural norm for the problem.
Journal ArticleDOI
Finite element analysis of the vibration problem of a plate coupled with a fluid
TL;DR: This work considers the approximation of the vibration modes of an elastic plate in contact with a compressible fluid and proves that spurious eigenvalues do not arise with this discretization of Reissner-Mindlin equations.
