Vibration Characteristics of Piezoelectric Microbeams Based on the Modified Couple Stress Theory

open access: yesShock and Vibration, 2014
The vibration behavior of piezoelectric microbeams is studied on the basis of the modified couple stress theory. The governing equations of motion and boundary conditions for the Euler-Bernoulli and Timoshenko beam models are derived using Hamilton’s ...

Exponential Stabilization for Timoshenko Beam with Distributed Delay in the Boundary Control

open access: yesAbstract and Applied Analysis, 2013
We consider the exponential stabilization for Timoshenko beam with distributed delay in the boundary control. Suppose that the controller outputs are of the form α1u1(t)+β1u1(t-τ)+∫-τ0‍g1(η)u1(t+η)dη and α2u2(t)+β2u2(t-τ)+∫-τ0‍g2(η)u2(t+η)dη; where u1(t)

Stability to double timoshenko thermoelastic beam

open access: yesZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik
AbstractIn this work, we study, from both analytical and numerical points of view, a thermoelastic problem involving two elastic beams, which are modeled by using the classical Timoshenko model. The resulting problem is written in terms of the transverse displacements, the angles of rotation, and the temperatures of the beams. The existence of a unique

Dynamic Stiffness Matrix for a Beam Element with Shear Deformation

open access: yesShock and Vibration, 1995
A method for calculating the dynamic transfer and stiffness matrices for a straight Timoshenko shear beam is presented. The method is applicable to beams with arbitrarily shaped cross sections and places no restrictions on the orientation of the element ...

On Dynamic Properties of Two Models of Beam on Nonlinear Foundation Subjected to Moving Load

open access: yesEngineering Transactions, 1993
The subjects of consideration are the infinite Bernoulli - Euler and Timoshenko models of a beam resting on a nonlinear visco-elastic foundation. The beams are subjected to a distributed inertialess loading constant in a given sector and moving with a ...
