Conception d’un essai purement inertiel pour la caractérisation du comportement dynamique de matériaux métalliques par la Méthode des Champs Virtuels
Abstract
The following work aims at designing a novel test to characterize the dynamic behaviour of metallic materials. Using the Virtual Fields Method (VFM), this test should enable the identification of elasticviscoplastic model that is valid on a wide strain and strain rate range. In order to do so, several test settings - including notably several specimen geometries - are simulated. Two criteria will govern the selection : (1) - the strain and the strain-rate range (2) - the identifiability of the parameters. Whereas the first criterion is rated with an advanced processing of the mechanical fields, the other is evaluated - based on FE simulations - reproducing the shooting procedure with a Ultra-High-Speed camera. Finally, the extraction of the material parameters demonstrates the relevance of the test setting
