Résumé
Le comportement d'uranium appauvri, uranium-molybdène, niobium, titane et rhenium a été étudié à grande vitesse de déformation sur barres d'Hopkinson. L'écaillage de ces matériaux a été également étudié. Une corélation entre la résistance à l'écaillage [MATH] et les propriétés d'écoulement a été trouvée.


Abstract
The mechanical behaviour of deplated uranium, uranium with molybdenum, niobium, titanium and rhenium was investigated under high strain rates. The Hopkinson split pressure bar was used. The spallation of these materials was also studied. The correlation of the spall strength, [MATH], with flow properties was found.
