Modern problems of biomechanics, in particular, the problems of modeling vision correction in ophthalmology are associated with the study of the stress-strain state of shells and plates made of complex materials. These problems are essentially nonlinear in geometry and in physical ... En savoir plus
It has been well proved that hydrogen represents a harmful element for steels because it can easily embrittle them. This phenomenon is known as Hydrogen Embrittelement (H.E.) and it leads to a serious decrease in mechanical properties especially loss of ductility. The studied material is ... En savoir plus
Joule-Thomson effect describes a change of temperature in a fluid due to a sudden change of pressure under adiabatic conditions. The aim of this study is to reproduce Joule-Thomson effect when an incompressible gas flows through a narrow pipe connecting two tanks at different pressures. ... En savoir plus
Although SF6 gas is characterized by a strong global warming potential, traditionally, it has been employed universally as the dielectric insulation gas for most electrical equipment because of its excellent technical performances. With the emergence of environmental regulations for ... En savoir plus
Shape and Topology Optimization of Loudspeaker Drivers This paper illustrates the use of formal mathematical optimization techniques for engineering solutions focused towards loudspeaker drivers. Both shape and topology optimization techniques are applied, with the physics ranging ... En savoir plus
Soft robotics allows for an increased flexibility and adaptability in the field of robotics, for example increased safety with regard to human-machine systems [1]. The Pneumatic Honeycomb Network (PHN) analyzed in this paper is a constitutive element in a new approach of dynamically ... En savoir plus
An auto-consistent multiphysical 3D model with strong coupling between Heat Transfer, Navier Stokes and ALE problems is proposed for the description of transient development of the keyhole and the melted zone in laser welding of metallic materials. It showed a satisfactory correspondence ... En savoir plus
Cylindrical grinding has become an integral part of machining of workpieces with an ultra-high precision and higher throughput. The grinding process involves the mechanical interaction of the grinding blade with the workpiece at relatively higher rotation speeds, with a higher energy ... En savoir plus
A lateral observation of laser-induced keyhole through the quartz window is an easy and cheap experimental method. It opens an interesting perspective for the study of keyhole asymmetry in case of dissimilar metal combinations. To quantify the effect of quartz window on the observed ... En savoir plus
The well-known Moore’s ‘Law’ sets a target for the down-scaling of silicon-based electronic devices. The down-scaling of devices may provide better performances, such as increased speed and lower power consumption that lead to a lower cost per bit. This is true for the processor ... En savoir plus
