An asymptotically optimal model for isotropic heterogeneous linearly elastic plates [PDF]
, 2004 In this paper, we derive and analyze a Reissner-Mindlin-like model for isotropic heterogeneous linearly elastic plates. The modeling procedure is based on a Hellinger-Reissner principle, which we modify to derive consistent models.

Two-scale Reissner-Mindlin plate model
Rakenteiden Mekaniikka, 2017 A two-scale plate model, in which the displacement assumption consists of the Reissner-Mindlin and warping parts, is presented. To reduce the modelling error of the classical Reissner-Mindlin model, the warping part is chosen so that the overall displacement satisfies the full 3D elasticity equations as well as possible.

Simultaneous analysis of continuously embedded Reissner–Mindlin shells in 3D bulk domains
International Journal for Numerical Methods in Engineering, Volume 125, Issue 16, 30 August 2024.Abstract A mechanical model and numerical method for the simultaneous analysis of Reissner–Mindlin shells with geometries implied by a continuous set of level sets (isosurfaces) over some three‐dimensional bulk domain is presented. A three‐dimensional mesh in the bulk domain is used in a tailored FEM formulation where the elements are by no means ...

A FE2 shell model with periodic boundary conditions for thin and thick shells
International Journal for Numerical Methods in Engineering, Volume 125, Issue 11, 15 June 2024.Abstract In this article a FE2 shell model for thin and thick shells within a first order homogenization scheme is presented. A variational formulation for the two‐scale boundary value problem and the associated finite element formulation is developed. Constraints with 5 or 9 Lagrange parameters are derived which eliminate both rigid body movements and

International Journal of Circuit Theory and Applications, Volume 52, Issue 6, Page 2985-2998, June 2024.The electrical analogs of moderately thick cross‐section beams and plates have been developed by considering shear stiffness and rotary inertia from higher order structural theories. The electrical analogs can be used in piezoelectric vibration damping.

Transverse shear parametrization in hierarchic large rotation shell formulations
International Journal for Numerical Methods in Engineering, Volume 125, Issue 9, 15 May 2024.Abstract Consistent treatment of large rotations in common Reissner–Mindlin formulations is a complicated task. Reissner–Mindlin formulations that use a hierarchic parametrization provide an elegant way to facilitate large rotation shell analyses. This can be achieved by the assumption of linearized transverse shear strains, resulting in an additive ...
