Experimental observation of dynamic ductile damage development under various triaxiality conditions - description of the principle

CEA, DAM, DIF, Bruyères-le-Châtel, 91297 Arpajon Cedex, France

Abstract

The Gurson model has been extended by Perrin to describe damage evolution in ductile viscoplastic materials. The so-called Gurson-Perrin model allows representing damage development with respect to strain-rate conditions. In order to fill a lack in current experimental procedures, we propose an experimental project able to test and validate the Gurson-Perrin model under various dynamic conditions and for different stress triaxiality levels.
