| Résumé | This paper presents an overview of the elevated temperature characterization of AA7075 aluminium sheet and calibration of a custom material model implemented in LS-DYNA. The plasticity characterization was performed by isothermal tensile testing while formability characterization was performed via isothermal Nakazima testing in a wide range of temperatures and strain rates. A special heat treatment path representative of the hot stamping was developed and applied in both series of tests. The material model included Hill'48 yield with a non-associated flow rule and phenomenological damage model similar to GISSMO but extended to cover non-isothermal conditions. |
