A specific experimental set-up making it possible to realize tests at velocities up to 9 m/s was used and specific specimens were designed to ensure security during impact. The choice of the specimen shape is discussed and the independence of the results to friction is highlighted. An inverse analysis of a finite element model is used to identify the parameters of a rheological law chosen to well-describe steel behavior at intermediate strain rates.
