Des essais d'impact de plaques ont été réalisés pour étudier le comportement élastique-plastique d'un fer pur dans une gamme de vitesse de déformation allant de 104s-1 à 106s-1 et pour des températures comprises entre 20°C et 500°C. La contrainte maximale atteinte dans les échantillons est de 60 kbar. Les comparaisons expérience-calcul montrent que 1) la limite d'écoulement et le module de cisaillement de ce matériau sont des fonctions décroissantes de la pression, 2) l'influence de la température sur le module de cisaillement est négligeable devant celle de la pression.Plate-impact experiments were used to investigate the elastic-plastic response of pure iron at strain rates ranging from 104s-1 to 106s-1 and temperatures ranging from 20°C ...
