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.

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

Equivalent beam analysis of thin-walled beam structures
Computers & Structures, 1987Abstract In the analysis of thin-walled beam structures it is often necessary to consider the effects of warping restraint in addition to the more usual actions of pure torsion, bending moment and axial force. Out-of-plane warping occurs as a result of twisting about the horizontal axis and, if restrained, may result in the development of large ...

Shear Lag And Beam Theories For Structures
2004Dynamic problems are solved using beam theory and shear lag approximations, and also FEM. For a laminated plate incorporating through-thickness fibers, highlights are: 1) Inertia complicates the fiber pullout problem considerably. 2) Disturbances propagate along frictionally coupled fibers at less than the bar wave speed.
