IDENTIFICATION OF A FORGING STEEL BEHAVIOR FROM DYNAMIC COMPRESSION TESTS
Abstract eng: This paper deals with compression tests carried out on a 50CD4 steel (norm EN 10 083) to char) and temperatures (200 to 400°C) acterize its behavior at strains (up to 2), strain rates (up to 50 corresponding to extrusion application. 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.
