Les modèles analytiques développés pour prédire le comportement balistique des aciers à blindage nécessitent la connaissance de la contrainte d'écoulement dynamique. Elle peut être mesurée à l'aide de l'essai d'impact du cylindre de Taylor car les vitesses de déformation atteintes sont proches de celles observées lors d'un tir balistique. Nous avons validé cette approche sur des aciers à blindage à très haute dureté, Mars 270 (550 HB) et Mars 300 (600 HB).In order to predict the ballistic behavior of armor steels with analytical models, dynamic flow stress of the materials is needed. We can measure it by a Taylor dynamic impact test with deformation speed close to those observed in ballistic impact. We used this average dynamic flow stress ...
