Damping of kink waves by mode coupling : I. Analytical treatment [PDF]
, 2013 Aims. To investigate the spatial damping of propagating kink waves in an inhomogeneous plasma. In the limit of a thin tube surrounded by a thin transition layer, an analytical formulation for kink waves driven in from the bottom boundary of the corona is

Advances in Materials Science and Engineering, 2018 New types of piezoelectric damping materials, including carbon nanotubes (CNTs)/lead magnesium niobate (PMN)/epoxy (EP) resin, are developed. The tan δ area (TA) analysis method is selected to evaluate the damping properties which obviously clarifies the

Mechanical behaviour and damping properties of Ni modified Cu–Zn–Al shape memory alloys
Journal of Science: Advanced Materials and Devices, 2018 The microstructure, mechanical behaviour and damping properties of Cu–18Zn–7Al–xNi alloys (where x = 0.1, 0.2, 0.3 and 0.4) were investigated. The Cu–Zn–Al alloys were produced by casting and then subjected to a homogenization – cold rolling – annealing ...

Dissipation mechanisms identification of soft hollow particle-dampers in honeycomb structures for micro-vibrations environment [PDF]
, 2009 Particle dampers are enclosures partially filled with metallic or glass small spheres, attached to the vibrating structure. This paper deals with replacing hard classical particles by soft hollow ones to maximize damping and mass ratio. Hence, one aspect

Numerical design and test on an assembled structure of a bolted joint with viscoelastic damping [PDF]
, 2015 Mechanical assemblies are subjected to many dynamic loads and modifications are often needed to achieve acceptable vibration levels. While modifications on mass and stiffness are well mastered, damping modifications are still considered difficult to ...

A study of joint damping in metal plates
, 2006 For satellite applications the determination of the correct dynamic behaviour and in particular the structural damping is important to assess the vibration environment for the spacecraft subsystems and ultimately their capability to withstand the launch ...
