Endurance of Damping Properties of Foam-Filled Tubes. [PDF]
Materials (Basel), 2015 The favorable energy-absorption properties of metal foams have been frequently proposed for damping or anti-crash applications. The aim of this paper is to investigate the endurance of these properties for composite structures, made by a metal or a hybrid metal-polymeric foam used as the core filling of a tubular metal case.

Shrinkage of frame polymer concretes in road construction [PDF]
E3S Web of Conferences, 2023 It is known that with the same raw material composition, it is possible to obtain different structures of composite materials. So, for example, polymer concretes can be made using traditional technology and the method of phase-by-phase forming.

Damping properties of the nucleus pulposus [PDF]
Clinical Biomechanics, 2012 The nucleus pulposus is extremely deformable and it is not uncommon to observe strain amplitudes as large as 12.5% in physiological loading conditions. It has been shown that the nucleus pulposus contributes to the damping properties of the intervertebral disc.

Damping properties of lead metaniobate [PDF]
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2001 Mechanical damping, tan delta, of lead metaniobate was determined experimentally over a wide range of frequency. Damping at audio and sub-audio frequency was lower than at ultrasonic frequency. The experiments were conducted in torsion and bending using an instrument capable of determining viscoelastic properties over more than 10 decades of time and ...

Effect of Heat Treatments and Carbon Content on the Damping Properties of Structural Steel
Journal of Engineering, 2023 Low- and medium-carbon structural steel components face random vibration and dynamic loads (like earthquakes) in many applications. Thus a modification to improve their mechanical properties, essentially damping properties, is required.
