A higher order triangular plate finite element using Airy functions

open access: yesAdvances in Mechanical Engineering, 2020
The present paper describes the formulation of a new moderately thick plate bending triangular finite element based on Mindlin–Reissner plate theory. It is called a Great Triangular Moderately Thick Plate Finite Element, or GTMTPFE.

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

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.

Robust topology optimization of thin plate structure under concentrated load with uncertain load position

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
This study investigates the robust topology optimization of a thin plate structure under a concentrated load with load position uncertainty. The effect of uncertain load direction, load magnitude, and load distribution in topology optimization problems ...

Modeling and Simulation Analysis of Rigid-flexible Coupling Dynamics of Ramming Mechanism Based on Reissner-Mindlin’s Medium-thick Plate Theory

open access: yesJournal of Physics: Conference Series, 2021
Abstract In order to obtain the dynamic characteristics of a ramming mechanism, the multi-rigid-body and rigid-flexible coupling dynamic models were established in Recurdyn. Considering the structural characteristics of the link, the deformation motion of the link is described by using the Reissner-Mindlin plate theory, and the dynamic ...
