Mechanical behavior of magnetically sensitive elastic structures in magnetic fields has received significant attentions from the scientific and engineering communities. Theoretical models on the bucking and bending of ferromagnetic beams, beam-plates, plates and conducting cylinders in transverse and /or oblique magnetic fields have been developed. A recent investigation employed nonlocal elasticity theory to study the effect of a longitudinal magnetic field on the transverse vibration of a magnetically sensitive double walled carbon nanotube (DWNT). Experimental and theoretical results have indicated closed agreement on the gross effects of magnetic fields on the vibrational characteristics of these magnetically sensitive structures.
Also, Layered Elastic Structures(LESs) held together by riveted and/or bolted connection suffice press- fit joints in structural mechanics and has received research attentions in the recent past A prompted gross interfacial slip motion in the presence of a frictional stress as influenced by interface pressure is inherently beneficial for vibration and noise dissipation in structures and engineering systems.
However, the effect of magnetic fields on the vibration and stability of laminated beams, beam-plates and plates have not been widely published in literatures. Interestingly, a paper recently reported the vibration of conducting two-layer sandwich homogeneous elastic beams in transverse fields. Notably, recent theoretical and experimental results were validated. In fact, the past arguments of large discrepancy between the theoretical predictions and experimental results arose from inexact mathematical theorization of these problems.
In furtherance to the quest to expand this frontiers of scientific knowledge, a Special Issue is proposed thematically: Theoretical and experimental papers with potential applications to suppress vibrations and noise from Jet Engines, Rocket Engines, Turbines, Industrial Machines and Power Plants are specially desired. Such papers are expected to begin with mathematical formulations and should highlights the combined effects of interface and external magnetic/electromagnetic pressures in conjunction with the roles of applied mechanical and LORENTZ forces pronouncedly.
