Effect of strain rate and stress triaxiality on fracture strain of 304 stainless steels for canister impact simulation
In this paper, smooth and notched bar tensile tests of austenitic stainless steel 304 are performed, covering four different multi-axial here stress states and six different strain rate conditions, to investigate the effect of the stress triaxiality and strain rate on fracture strain.Test data show that the measured true fracture strain tends to de
