How to model orthotropic materials by the Discrete Element Method (DEM): random sphere packing or regular cubic arrangement?

CURTI, Rémi; LORONG, Philippe; POT, Guillaume; GIRARDON, Stéphane (Springer, 2018)

The discrete element method (DEM) is used for continuous material modeling. The method is based on discretizing mass material into small elements, usually spheres, which are linked to their neighbours through bonds. If DEM ...
Investigation of the Effect of Residual Stress Gradient on the Wear Behavior of PVD Thin Films

TLILI, Brahim; NOUVEAU, Corinne; GUILLEMOT, Gildas; BESNARD, Aurélien; BARKAOUI, Abdelwahed (Springer, 2018)

The control of residual stresses has been seldom investigated in multilayer coatings dedicated to improvement of wear behavior. Here, we report the preparation and characterization of superposed structures composed of Cr, ...
Phenomenological study of multivariable effects on exit burr criteria during orthogonal cutting of AlSi alloys using principal components analysis

RÉGNIER, Tristan; FROMENTIN, Guillaume; D'ACUNTO, Alain; OUTEIRO, José; MARCON, Bertrand; CROLET, Arnaud (ASME American Society of Mechanical Engineers, 2018)

During machining, burrs are produced along a part’s edges, which can affect a final product lifetime or its efficiency. Moreover, time-consuming and expensive techniques are needed to be applied to remove such burrs. ...
Effect of grain direction on cutting forces and chip geometry during green beech wood machining

CURTI, Rémi; MARCON, Bertrand; DENAUD, Louis; COLLET, Robert (BioResources, 2018)

Proper valorization of the sawing wastes in industrial sawmills is a permanent issue with strong economic and environmental stakes. Most industrial sawmills are equipped with chipper-canter heads reducing the outer part ...
An innovative method based on grain angle measurement to sort veneer and predict mechanical properties of beech laminated veneer lumber

VIGUIER, Joffrey; BOURGEAY, Christophe; ROHUMAA, Anti; POT, Guillaume; DENAUD, Louis (Elsevier, 2018)

This study proposes an innovative model based on local grain angle measurements to predict the modulus of elasticity of LVL made from beech. It includes a veneers sorting method industrially compatible thanks to its low ...
Deoxidation Impact on Non-Metallic Inclusions and Characterization Methods

NICOLI, Cécile; CARTON, Jean-François; VAUCHERET, Alexis; JACQUET, Philippe (AGH University of Science and Technology Press, AGH-UST, 30 Mickiewicza Av., 30-059 Krakow, 2018)

Deoxidation is an unavoidable step in the elaboration of steel. The study of its influence could improve the quality of low-carbon steel (0.20–0.25 wt.% of carbon). There are many deoxidation methods, and the most-common ...
Temperature measurement inside and near the weld pool during laser welding

LHOSPITALIER, Sylvie; LAMBERTIN, Michel; QUESADA, Jean; BERT, Alexandre; BOURGES, Philippe (Laser Institute of America, 1999)

The work in this article deals with the measurement of temperature fields inside and near the weld pool during laser welding. The laser source used for this study is a 7.5 kW CO2 laser, and the welded material is a UNS ...
