Despite its development over the past several years, Additive Manufacturing (AM) has not yet unveiled its full potential for sustainable manufacturing. The recent awareness of the environmental impact of products we consume have allowed researchers to lay the first foundations for sustainable AM. Sustainable manufacturing of products necessarily re...
China Scholarship Council (CSC). / Strain localization is an important plastic instability process occurring prior to fracture. It is usually observed in the form of narrow bands of intense plastic shear strain in deformed bodies undergoing severe inhomogeneous deformation. Considering a single crystal with single slip system activated, two types o...
This study considers quality aspects in the process planning of a reconfigurable manufacturing system. The goal is to analyze how the variation in quality impacts the process planning, i.e., cost-based design and modular features. Besides this, the analysis helps in identifying the number of conforming and failed products delivered by a process pla...
This article proposes a novel mean for tuning the natural frequency of an electromagnetic resonant shunt, using a pulse-width modulation (PWM) circuit. It is used to modulate the value of the capacitance of the shunt, and the electrical frequency is shown to be proportional to the command parameter of the PWM, the duty cycle. An easy and efficient ...
The accuracy of a machining model depends on the capability of this model to describe the physical phenomena associated to the real machining system. This includes the material constitutive model and the approach used to describe the feld flow of the material in cutting. In this paper, a model of high speed machining (HSM) of Ti6Al4V titanium alloy ...
Weld toes and weld roots of continuously welded structures subjected to cyclic loading are critical zones in terms of the fatigue resistance. The finite element method coupled with a fatigue criterion is commonly used to ensure the correct sizing and fatigue design of welded structures. However, weld geometries are often simplified or idealized to ...
Vibration characteristics of elastic nanostructures embedded in fluid medium have been used for biological and mechanical sensing and also to investigate materials and mechanical properties. An analytical approach has been developed in this paper to accurately predict toroidal vibrations of an elastic nanosphere in water–glycerol mixture. The Maxwe...
Nowadays, numerical simulations are more and more used in forging industry, and their predictability is validated through a comparison with experiments. But sometimes simulations and experiments provide significantly different results. And quite often, the models implemented in simulations are taken for responsible of this divergence with experimen...
This paper aims to investigate the effect of water absorption on the cutting behavior of biocomposites using flax fiber reinforced polylactic-acid (PLA) and the orthogonal cutting process. Different immersion times have been considered from 1 to 150 days in order to investigate both transient and saturated hygrometric regimes. Machining forces are ...
De nos jours, les simulations numériques sont de plus en plus utilisées dans l’industrie de la forge, et leur prédictibilité est validée grâce à des comparaisons avec des campagnes expérimentales. Il arrive cependant parfois que les résultats expérimentaux et numériques soient significativement différents. Dans ce contexte se sont bien souvent les ...
