A study on structural analysis of composite beam structure
Materials Today: Proceedings, 2021Abstract The active damping of structures is an important emerging field. In this context, it is necessary to be able to develop new control methods for flexible structures and simulate their effects. In order to be able to deal with the optimization of active device locations, spill over and any other general problems linked to control and model ...

The presentation of the finite element method starts in this chapter with the explanation of the finite element method for truss and beam systems. The concept of stiffness matrices is shown first for a simple truss element. The procedure for setting up the equations for a finite element analysis is explained exemplary for a simple truss system.

Optical binding and the influence of beam structure
Optics Letters, 2008An optically induced interparticle potential, applicable to particles of any shape, is derived in a formulation that accommodates the effects of beam structure. The theory allows the consideration of optical binding interactions in beams of spatially varying irradiance and polarization.

Structuring Erlang BEAM control flow
Proceedings of the 16th ACM SIGPLAN International Workshop on Erlang, 2017As source code dependencies are usually stored in some precompiled executable representation like bytecode, static analysis frameworks for high-level languages have to be specifically adapted so they can meaningfully analyse these libraries too. This adaptation is not trivial, since compilation is in general not injective, the semantics of low-level ...

Beam shifts to reflected light beams and their axial structure
SPIE Proceedings, 2014The similarities and differences of spatial shifts to the centroids of reflected beams, and their (optical vortex) structure are discussed and reviewed. The differences between vortex-induced shifts to a beam centroid on reflection, and to the distribution of the vortices themselves is discussed. We conclude by discussing the shifts of a reflected beam

We treat the dynamics of beams in a manner similar to that for rods. The sequence of analysis followed is: derive the governing differential equations, use spectral analysis to obtain general solutions, obtain an exact matrix formulation, obtain an approximate matrix formulation.

Beam-Plasma Structures at Propagation of Electron Beams in Plasma
Physica Scripta, 1998In the frame of the theory of weak turbulence the propagation of electron beams is considered. Using the smallness of quasilinear time transition from kinetic equations to gas-dynamic ones has been done. The obtained gas-dynamic equations are solved for one, two and N monoenergetic beams. It is shown that each beam generally propagates as a beam-plasma

Photonic crystal structures: Beam deflector and beam router
Chinese Physics B, 2018We investigate the optical characteristic, transverse magnetic (TM) and transverse electric (TE) band of two-dimensional (2D) square lattice photonic crystal structure, which is composed of cylindrical air regions positioned at the corners of the square shaped dielectric rods.

Beam structure studies of low-energy ion beams
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1991Abstract The ion beam structure at various axial positions along the beam-transport line has been monitored and studied utilizing a fluor screen and a video camera. The fluor material is aluminum oxide that is plasma-jet sprayed onto the surface of an aluminum or a water-cooled copper substrate.

Application to Beam Structures
3.1 Introduction Applying the inverse differential quadrature method (iDQM) to a wide range of one-dimensional (1D) problems is important to establish iDQM as a robust solution strategy. In this context, this chapter considers numerical analysis of beam structures, which constitutes one of ...Saheed O. Ojo +3 more
