Accurate characterization of the mass transport properties of additively processed sand molds is essential in order to achieve reproducibility of the produced castings and control of gas defects in foundry industries. The present work highlights the potential use of X-ray micro-computed tomography (μ-CT) to characterize the evolution of permeabilit...
Although all collider experimental observations are theoretically explained by the standard model (SM) of particle physics, the SM does not explain many natural phenomenon, such as gravity, dark matter, dark energy, matter-antimatter asymmetry, etc. SuperSymmetry (SUSY) is an extension of the SM that can address some of the issues in SM. The minima...
An analytical approach of the propagation and attenuation of Love waves in a viscoelastic liquidsaturated poroelastic layer has been considered in this paper. The equations of motion have been formulated separately for different media under suitable boundary conditions at the interface of viscoelastic liquid, poroelastic layer and elastic substrate...
The aim of this study is to evaluate the effect of the loading rate on the mechanical properties and damage mechanisms of a Glass/Elium150 laminate composite. Quasi-static indentation (QS) and low energy dynamic impact (DYN) tests which simulate lifetime structural loadings (dropped tool, gravel impacts, …) are lead. A specific experimental approac...

As they contain air from past atmospheres, ice cores are unparalleled climate paleo-archives. The study of the gases enclosed in ice cores from the arid region of East Antarctica allows to infer the past compositions of the atmosphere back to 800,000 years ago. Gases are trapped during the compaction of the snow deposited on top of the ice sheet. I...

Multiple parameters influence the durability of reinforced thermoplastics under fatigue loading. Having models unifying as many of these parameters, while providing an accurate estimation of the fatigue lifetime, is thus key. This investigation on the evolution of multiple mechanical parameters under cyclic loading, and based on a large experimenta...
Selective Laser Melting (SLM) is a powder bed fusion process which allows to build-up parts by successive addition of layers using 3D-CAD models. Among the advantages, the high degree of freedom for part design and the small loss of material explain the increasing number of Ti-6Al-4V parts obtained by this process. However, right after additive man...
Cast aluminium alloys have a key position as structural materials for the automotive industry combining good mechanical performance, excellent castability and thermal conductivity, making them a suitable choice for engine parts such as cylinder heads. In this paper, the low-cycle fatigue behaviour of a cast aluminium alloys is investigated at ambie...
