“…Results on 4340 steel showed that the dynamic flow curve is significantly different from the static curve [10,11]. Elastic-perfectly plastic curves having higher yield strengths gave successively better agreement with the measured profiles, especially near the impact interface.…”

“…On se trouve là dans une démarche de validation, où la confrontation expérience-calcul tient une place éminente, ce qui montre bien le rôle du calcul en dynamique. Moyennant une approche inverse, certaines expériences permettent une identification partielle, bien que la prudence soit de rigueur pour de telles approches (voir par exemple le cas de l'essai de Taylor [35]). Enfin, les analyses post-mortem peuvent s'avérer délicates dans le cas dynamique.…”

“…From the dimensions of the deformed specimen, Taylor provides an estimate of the dynamic yield strength. Since, it has been mostly used to validate constitutive models at strain rate ranging from 10 3 to 10 4 s -1 , and to evaluate dynamic failure properties of materials [2][3][4]. Two kinds of failure processes have been observed with the Taylor specimens.…”
