On a Thermoelastic Laminated Timoshenko Beam: Well Posedness and Stability

open access: yesComplexity, 2020
In this paper, we are concerned with a linear thermoelastic laminated Timoshenko beam, where the heat conduction is given by Cattaneo’s law. We firstly prove the global well posedness of the system.

Symmetry group classification and optimal reduction of a class of damped Timoshenko beam system with a nonlinear rotational moment [PDF]

open access: yesarXiv, 2016
We consider a nonlinear Timoshenko system of partial differential equations (PDEs) with a frictional damping term in rotation angle. The nonlinearity is due to the arbitrary dependence on the rotation moment. A Lie symmetry group classification of the arbitrary function of rotation moment is presented.

Block Backstepping for Isotachic Hyperbolic PDEs and Multilayer Timoshenko Beams [PDF]

open access: yesarXiv, 2023
In this paper, we investigate the rapid stabilization of N-layer Timoshenko composite beams with anti-damping and anti-stiffness at the uncontrolled boundaries. The problem of stabilization for a two-layer composite beam has been previously studied by transforming the model into a 1-D hyperbolic PIDE-ODE form and then applying backstepping to this new ...

Parameter identification in prestressed concrete beams by incremental beam–column equation and physics‐informed neural networks

open access: yesComputer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract This paper explores a novel methodology for identifying prestress force (and bending rigidity) from the perspective of static deflection methods and derives an incremental beam–column equation (iBCE) by elucidating the mechanisms underlying the long‐ and short‐term behaviors, with particular emphasis on a physical system that disregards long ...

Seismic Design of Hybrid Coupled CLT Shear Walls with Steel Link Beams

open access: yesEarthquake Engineering &Structural Dynamics, Volume 54, Issue 6, Page 1520-1539, May 2025.
ABSTRACT This study proposes a seismic design method for hybrid coupled cross‐laminated timber (CLT) shear walls with steel link beams as the lateral load‐resisting system for mass timber buildings. A force‐based seismic design method was proposed as a preliminary design process to determine the primary structural components. To inform the selection of

A 3D Macroporous Carbon NiCu Single‐Atom Catalyst for High Current Density CO2 Electroreduction

open access: yesAdvanced Functional Materials, Volume 35, Issue 14, April 3, 2025.
A hard‐template 2‐step pyrolysis method is proposed for the fabrication of highly dispersed Ni and Cu atomic active sites on a 3D macroporous carbon matrix in which Ni serves as an active site and Cu as a regulator for selective CO2 electroreduction to CO.
