An asymptotic Reissner–Mindlin plate model
Comptes Rendus. Mécanique, 2018 A mathematical study via variational convergence of a periodic distribution of classical linearly elastic thin plates softly abutted together shows that it is not necessary to use a different continuum model nor to make constitutive symmetry hypothesis as starting points to deduce the Reissner–Mindlin plate model.

International Journal for Computational Civil and Structural Engineering, 2021 This paper proposes a method for creating finite elements with simultaneous approximation of functions corresponding to displacements and rotations. New triangular and quadrangular finite elements have been created, which can have additional nodes on the

Vietnam Journal of Mechanics, 2018 A cell-based smoothed discrete shear gap method (CS-DSG3) using three-node triangular elements was recently proposed to improve the performance of the discrete shear gap method (DSG3) for static and free vibration analyses of isotropic Reissner-Mindlin ...

A bending-gradient model for thick plates, I : theory [PDF]
, 2011 International audienceThis is the first part of a two-part paper dedicated to a new plate theory for out-of-plane loaded thick plates where the static unknowns are those of the Kirchhoff-Love theory (3 in-plane stresses and 3 bending moments), to which six

An overview of selected plate and shell FE models with graphic presentation of governing relations
Computer Assisted Methods in Engineering and Science, 2022 A survey of three forms (strong, weak and variational) of mathematical models is presented using expressive diagrams initiated in [3,10]. The primary and intermediate variables, governing field equations, constraint equations and variables specified by ...

An improved theory of laminated Reissner–Mindlin plates
International Journal of Solids and Structures, 2014 AbstractTheories of laminated plates have been proposed that, although they lead to different plate equations, are based as ours on the assumptions that the three-dimensional deformation of each layer is of Reissner–Mindlin type and that displacement and traction vectors are continuous across layer interfaces.

Bisector and zero-macrospin co-rotational systems for shell elements [PDF]
, 2015 A principal issue in any co-rotational approach for large displacement analysis of plates and shells is associated with the specific choice of the local reference system in relation to the current deformed element configuration.
