Arbitrary decay for a nonlinear Euler-Bernoulli beam with neutral delay [PDF]

Theoretical and Applied Mechanics, 2023
In this paper, the free transverse vibration of a nonlinear Euler- Bernoulli beam under a neutral type delay is considered. In order to suppress the beam transverse vibrations, a boundary control based on the Lyapunov method is designed.

Stabilization analysis of Euler-Bernoulli beam equation with locally distributed disturbance

Journal of Hebei University of Science and Technology, 2017
In order to enrich the system stability theory of the control theories, taking Euler-Bernoulli beam equation as the research subject, the stability of Euler-Bernoulli beam equation with locally distributed disturbance is studied.

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

Shock 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 ...

Wave propagation characteristics in nanoporous metal foam nanobeams

Results in Physics, 2019
This research is devoted to the wave propagation characteristics analysis of nanobeams made of nanoporous metal foams. Three nanoporosity distribution models, namely, symmetry, asymmetry and uniform distributions, are taken into account.

Modal Formulation of Segmented Euler-Bernoulli Beams [PDF]

Mathematical Problems in Engineering, 2007
We consider the obtention of modes and frequencies of segmented Euler-Bernoulli beams with internal damping and external viscous damping at the discontinuities of the sections. This is done by following a Newtonian approach in terms of a fundamental response of stationary beams subject to both types of damping.

Non-linear vibration of Euler-Bernoulli beams [PDF]

Latin American Journal of Solids and Structures, 2011
In this paper, variational iteration (VIM) and parametrized perturbation (PPM) methods have been used to investigate non-linear vibration of Euler-Bernoulli beams subjected to the axial loads. The proposed methods do not require small parameter in the equation which is difficult to be found for nonlinear problems.

Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...
