On Stability of Hyperbolic Thermoelastic Reissner-Mindlin-Timoshenko Plates

, 2013
In the present article, we consider a thermoelastic plate of Reissner-Mindlin-Timoshenko type with the hyperbolic heat conduction arising from Cattaneo's law. In the absense of any additional mechanical dissipations, the system is often not even strongly

Damage Identification in Large‐Scale Structures Using Time Series Analysis and Improved Sparse Regularization

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
The academic community has paid much attention to the research topic of structural health monitoring (SHM) and damage identification for several decades, which flourishes the development of diverse damage identification approaches. The sensitivity‐based damage identification enjoys popularity due to its clear physical meaning and long development ...

Nonintrusive coupling of 3D and 2D laminated composite models based on finite element 3D recovery

, 2014
In order to simulate the mechanical behavior of large structures assembled from thin composite panels, we propose a coupling technique which substitutes local 3D models for the global plate model in the critical zones where plate modeling is inadequate ...

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 ...

On the use of finite strip method for buckling analysis of moderately thick plate by refined plate theory and using new types of functions

Latin American Journal of Solids and Structures
A numerical method is developed for the buckling analysis of moderately thick plate with different boundary conditions. The procedure use the finite strip method in conjunction with the refined plate theory (RPT).

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

Finite Element Analysis of Functionally Graded Mindlin–Reissner Plates for Aircraft Tapered and Interpolated Wing Defluxion and Modal Analysis

Mathematics
This paper explores and discusses how wing structures vibrate by using the Mindlin–Reissner plate theory, which takes into consideration the effects of transverse shear deformation and rotary inertia.

A multilayer anisotropic plate model with warping functions for the study of vibrations reformulated from Woodcock's work

, 2012
In this paper, a plate model suitable for static and dynamic analysis of inhomogeneous anisotropic multilayered plates is described. This model takes transverse shear variation through the thickness of the plate into account by means of warping functions

The effects of shear deformation and rotary inertia on the electrical analogs of beams and plates for multimodal piezoelectric damping

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.

An asymptotic strain gradient Reissner-Mindlin plate model [PDF]

, 2013
In this paper we derive a strain gradient plate model from the three-dimensional equations of strain gradient linearized elasticity. The deduction is based on the asymptotic analysis with respect of a small real parameter being the thickness of the ...
