Geometrical Nonlinearity for a Timoshenko Beam with Flexoelectricity
Nanomaterials, 2021 The Timoshenko beam model is applied to the analysis of the flexoelectric effect for a cantilever beam under large deformations. The geometric nonlinearity with von Kármán strains is considered.

Finite Element Modeling for Buckling Analysis of Tapered Axially Functionally Graded Timoshenko Beam on Elastic Foundation [PDF]
Mechanics of Advanced Composite Structures, 2020 In this study, an efficient finite element model with two degrees of freedom per node is developed for buckling analysis of axially functionally graded (AFG) tapered Timoshenko beams resting on Winkler elastic foundation.

Timoshenko Beams and the Hamiltonian System
IOP Conference Series: Earth and Environmental Science, 2020 Abstract The significance of the transition from Lagrangian system to Hamiltonian system lies in that it has entered the form of symplectic geometry from the traditional Euclidean geometry and broken through the traditional concept, so that the dual mixed variable method has entered into the vast field of applied mechanics.

Asymptotics and stabilization for dynamic models of nonlinear beams; pp. 150–155 [PDF]
Proceedings of the Estonian Academy of Sciences, 2010 We prove that the von Kármán model for vibrating beams can be obtained as a singular limit of a modified MindlinâTimoshenko system when the modulus of elasticity in shear k tends to infinity, provided a regularizing term through a fourth-order ...

Lateral-Mode Vibration of Microcantilever-Based Sensors in Viscous Fluids Using Timoshenko Beam Theory [PDF]
, 2014 To more accurately model microcantilever resonant behavior in liquids and to improve lateral-mode sensor performance, a new model is developed to incorporate viscous fluid effects and Timoshenko beam effects (shear deformation, rotatory inertia).

Dynamic behavior of a rotating delaminated composite beam including rotary inertia and shear deformation effects [PDF]
, 2015 A finite element (FE) model is developed to study the free vibration of a rotating laminated composite beam with a single delamination. The rotary inertia and shear deformation effects, as well as the bending–extension, bending–twist and extension–twist ...
