A Thefftz patch recovery method for smooth stress resultants and applications to Reissner-Mindlin equilibrium plate models

open access: yesComputer Assisted Methods in Engineering and Science, 2023
A method is proposed for smoothing approximate fields of stress-resultants in patches of finite elements. The method is based on combining Trefftz fields of stress-resultants in a p-version so as to obtain a closest fit using the strain energy norm as a

A General Ritz Algorithm for Static Analysis of Arbitrary Laminated Composite Plates using First Order Shear Deformation Theory

open access: yesThe Journal of Engineering Research, 2013
This paper is concerned with the bending of laminated composite plates with arbitrary lay-up and general boundary conditions. The analysis is based on the small deflection, first-order shear deformation theory of composite plates, which utilizes the ...

Stress intensity factors computation for bending plates with extended finite element method [PDF]

open access: yes, 2012
The modelization of bending plates with through-the-thickness cracks is investigated. We consider the Kirchhoff–Love plate model, which is valid for very thin plates.

Numerical results for mimetic discretization of Reissner-Mindlin plate problems [PDF]

open access: yes, 2012
A low-order mimetic finite difference (MFD) method for Reissner-Mindlin plate problems is considered. Together with the source problem, the free vibration and the buckling problems are investigated.

A 4-node quadrilateral element with center-point based discrete shear gap (CP-DSG4)

open access: yesVietnam Journal of Mechanics, 2021
This work aims at presenting a novel four-node quadrilateral element, which is enhanced by integrating with discrete shear gap (DSG), for analysis of Reissner-Mindlin plates. In contrast to previous studies that are mainly based on three-node triangular

Application of the curvature smoothing technique for four-node quadrilateral Reissner-Mindlin plate element

open access: yesVietnam Journal of Mechanics, 2007
A quadrilateral element with smoothed curvatures for Reissner-Mindlin structure plates is proposed. A curvature matrix at an arbitrary point is normalized by a non-local approximation over a smoothing function.
