Buckling of Planar Micro-Structured Beams [PDF]

Applied Sciences, 2020
In this paper, a Timoshenko beam model is formulated for buckling analysis of periodic micro-structured beams, uniformly compressed. These are planar grid beams, whose micro-structure consists of a square lattice of equal fibers, modeled as Timoshenko micro-beams.

Effects of Structural Parameters on the Dynamics of a Beam Structure with a Beam-Type Vibration Absorber [PDF]

Advances in Acoustics and Vibration, 2012
A beam-type absorber has been known as one of the dynamic vibration absorbers used to suppress excessive vibration of an engineering structure. This paper studies an absorbing beam which is attached through a visco-elastic layer on a primary beam structure.

Effects of misalignments in the optical vortex transformation performed by holograms with embedded phase singularity

, 2010
Spatial characteristics of diffracted beams produced by a "fork" hologram from an incident circular Laguerre-Gaussian beam whose axis differ from the hologram optical axis are studied theoretically.

Shadows of structured beams in lenslike media

Optics Express, 2023
The self-healing phenomenon of structured light beams has been comprehensively investigated for its important role in various applications including optical tweezing, superresolution imaging, and optical communication. However, for different structured beams, there are different explanations for the self-healing effect, and a unified theory has not yet

Early out-of-equilibrium beam-plasma evolution

, 2006
We solve analytically the out-of-equilibrium initial stage that follows the injection of a radially finite electron beam into a plasma at rest and test it against particle-in-cell simulations.
