Working on the damping of sandwich beams, Adams and Maheri [15] introduced a test methodology for obtaining the shear modulus and damping of honeycomb materials. In a later work [6], they used essentially the Adams-Bacon model to compute the individual contributions to the overall damping in ...
Study on Improvement of Damping in Jointed Cantilever Beams Using FEM Damping in built-up structures is produced by the energy dissipation due to micro-slip along the frictional interfaces. The analysis of the problem has been carried out using Finite Element Method (FEM). A finite element model...

For small displacements, the quadratic part of the damping function becomes negligible and the damping forces can be assumed to be linear. Consequently, the FRF for the small displacement become independent from the input amplitudes. In addition, it is worth mentioning that, while random input ...
Thus, passive fault-tolerant control can avoid the time delay caused by fault detection and reconfiguration mechanisms, and can improve the reliability of control system. Many advanced control theories can be used in the design of passive fault-tolerant controllers for AHV. Refs. 48, 49 designed ...
2. The connection damping between parts in the model is viscous damping. 3. The front sections of the front and rear rocker arms are beams with no mass, which are connected to the front and rear drums, respectively. 4. The influence of the electrical system, hydraulic system and transmi...
In a typical LIGS experiment, two coherent pump beams from the same pulsed laser source are crossed and create an interference pattern in the intersection region. A laser-induced grating (LIG) can be formed by two different mechanisms: (1) thermalization of the absorbed laser radiation by ...
Power flows in by means of hydrodynamic excitation and power flows out due to three different damping mechanisms: structural, hydrodynamic, and wave radiation. It is well known that crossflow and inline forces and motions are coupled. This coupling influences the magnitude and frequency content of ...
Γcor is a correction term which we add to the damping factor in order to adjust theoretical formulae by considering experimental data. Two first terms of Eq. (9) are related to the dominant dissipation mechanisms for the bulk metal system which should be corrected for the limited size of ...
