Introduction Present paper gives a comparison of the Upperconvected Maxwell (UCM) and the Oldroyd-B model for the calculation of dissipation in high shear-rate cases of viscodampers. When polymeric liquid is considered that part of energy that is irreversible can not be calculated in the ... En savoir plus
Introduction: Lithium-ion batteries are widely used as power sources for portable electronic devices (laptop, phones, and players) and electric cars due to their high energy density. New applications, such as Formula E, require also a huge power capability that the iron-phosphate-based ... En savoir plus
Plasma torches are used in processing of materials and in energy industry for producing plasma. In a non-transferred arc plasma torch, an electric arc can be glowed by applying a direct current (DC) between the cathode and anode, both placed inside the torch. Then, the plasma (Fig. 1) is ...

Metal foams are interesting materials with many potential applications. Foamed metals or alloys include gas voids in the material structure and therefore the density is introduced as a new variable, with the real possibility to modify ad hoc their physical properties. In the indirect ... En savoir plus
When an electronic device is worn for extended periods, possibly in direct contact with human skin, heat must be safely transferred away from the device, without exceeding standards and regulatory temperature limits on the skin and on the exposed surfaces of the device. Heat transfer is ... En savoir plus
Intervertebral discs (IVD) are fibro-cartilages situated between vertebrae providing their joint flexibility. They play a major role in the transmission and absorption of load through the spine. The disc can undergo progressive structural and quantitative changes in its composition and ... En savoir plus
Introduction: The drawbacks of most commercial “advanced battery” solutions are high price, danger, and low recyclability. The most cost efficient, environmental-friendly, and safest solutions so far is based on lead-acid electrochemistry, a proven technology for more than 150 years. Key ... En savoir plus
In order to predict the residual mechanical state of assemblies during pulsed laser welding, mechanical and metallurgical behaviors of materials need to be precisely characterized. Based on experimental data and analyses [1], a numerical model is developed in COMSOL Multiphysics® ... En savoir plus
Electrostatic precipitators (ESP) are a reliable technology to control emissions of airborne particles in a series of applications such as coal-fired power plants, cement plants or even for domestic fireplaces. Numerical calculations allow further development of electrostatic ... En savoir plus
In inductive heating simulations the electromagnetic properties of the steel have a significant impact on the temperature pattern along the heated product. Indeed, taking into account the non-linearity of the ferromagnetic material properties is a key point to have relevant simulation ... En savoir plus
