Dissipation energy in sound-absorbing poroelastic material

open access: yesNihon Kikai Gakkai ronbunshu, 2020
In sound-absorbing poro-elastic media, the energy of incident sound wave is dissipated through the following three mechanisms: the viscous dissipation arising the vicinity of the boundary between the solid and fluid phases due to the viscosity of air ...

An experimental method for estimating the tearing energy in rubber-like materials using the true stored energy

open access: yesScientific Reports, 2021
A method for determining the critical tearing energy in rubber-like materials is proposed. In this method, the energy required for crack propagation in a rubber-like material is determined by the change of recovered elastic energy which is obtained by ...

Overview of the Potential of Energy Harvesting Sources in Electric Vehicles

open access: yesEnergies, 2023
Energy harvesting, a cutting-edge technology that captures wasted energy from vehicles, constitutes a means to improve the efficiency of electric vehicles. Dissipated energy can be converted into electricity using regenerative energy recovery systems and

Dissipation as a mechanism of energy gain [PDF]

open access: yesPhysical Review E, 2008
Some properties of the annular billiard under the presence of weak dissipation are studied. We show, in a dissipative system, that the average energy of a particle acquires higher values than its average energy of the conservative case. The creation of attractors, associated with a chaotic dynamics in the conservative regime, both in appropriated ...

Energy evolution and water immersion-induced weakening in sandstone roof of coal mines

open access: yesInternational Journal of Coal Science & Technology, 2022
The instability of underground spaces in abandoned coal mines with water-immersed rocks is one of the main hazards hindering the geothermal energy use and ecological restoration of post-mining areas.

Ventilation for low dissipated energy achieved using flow control during both inspiration and expiration

open access: yesTrends in Anaesthesia and Critical Care, 2019
Mechanical or thermal stresses, which cause injury, do so essentially by dissipating energy in the tissue at a rate above some threshold at which damage occurs. This principle may also be applied to a ventilated lung.

Identification of the dissipated energy by friction in dynamic multibody systems [PDF]

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2008
This paper is devoted to the modeling of finite deformations of elastic bodies under contact/impact conditions. In this kind of applications, it is well known that the total energy will be reduced versus time because of frictional effects.
