Analysis of the thermoviscoelastic Timoshenko system with diffusion effect
Partial Differential Equations in Applied Mathematics, 2021 This paper is concerned with a new Timoshenko beam model with thermal, mass diffusion and viscoelastic effects. First, by the C0-semigroup theory, we prove the well posedness of the considered problem with Dirichlet boundary conditions.

Stability of Timoshenko systems with past history
Journal of Mathematical Analysis and Applications, 2008 The paper deals with linear one-dimensional integro-differential vibrating systems of the Timoshenko type with past history acting only in one equation. The authors show that the dissipation given by the history term is strong enough to produce the exponential stability of the considered systems if and only if the equations have the same wave speeds ...

Elastoplastic Timoshenko beams [PDF]
, 2009 A Timoshenko type elastoplastic beam equation is derived by dimensional reduction from a general 3D system with von Mises plasticity law. It consists of two second-order hyperbolic equations with an anisotropic vectorial Prandtl--Ishlinskii hysteresis ...

Nonlinear Vibration Characteristic Analysis of Electric Vehicle–Road Coupling System
International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT In‐wheel motor drive is the developing direction of automobile electrification and intelligence. However, the increased unsprung mass in in‐wheel motor‐driven electric vehicles (IWMEVs) leads to higher dynamic tire loads, thereby intensifying vehicle–road coupling interactions. To address this problem, an 11‐degree‐of‐freedom nonlinear dynamic
