Special Issue Information
Dear Colleagues,
In many structural applications, such as aircraft and space structures, automotive and naval vehicles, engine blades, and high-speed machinery, the reduction of structural vibration, sound control, aeroelastic stability, fatigue endurance, and impact resistance are requested to increase structural system performance, and they are usually achieved through the use of passive approaches.
An accurate dynamic response prediction of passive damped structures should yield high damping performance by adding minimal weight. In order to reduce and control the vibration response of lightweight and flexible structures, an effective solution is the use of polymer matrix composite structures, a kind of materials which exhibits higher damping properties and is lighter with respect to metals. Moreover, multilayered configurations of composite layers with viscoelastic intersheets further improve passive damping capabilities. Alternative solutions consider sandwich structures with composite skins and foam cores or viscoelastic polymer layers in order to use the main energy loss mechanism due to the transverse shear behavior of the viscoelastic layers.
In the 1950s, it was observed in many experiments that structural damping is higher in multilayered structures embedding viscoelastic sheets. Most numerical models used to simulate the viscoelastic material response are based on proportional damping with respect to structural stiffness and mass properties. In recent years, more sophisticated mathematical models, such as fractional derivatives models, have been developed in order to simulate the behavior of real viscoelastic materials.
We believe that the increasing interest in finding new mathematical models for real viscoelastic materials will also depend on the performance of materials employed and the development of new materials with viscoelastic damping properties. Aiming to highlight this concept, this Special Issue will focus on viscoelastic composite materials modeling, and manufacturing techniques for the production of materials with viscoelastic damping properties, as well as featuring emerging material-based developments.
We kindly invite you to submit a manuscript(s) for this Special Issue. Full papers, communications, and reviews are all welcome.
