Failure mechanisms in high strength steel under impact loading: from ASB to full fracture

Abstract : Impact tests on pre-notched plates are carried out to analyze qualitatively and quantitatively the crack development in high strength steel under high loading rate. Implementation of ultra-high speed camera (1M frame/s) allows on one hand observing the chronology of the failure mechanisms from adiabatic-shear-banding until full fracture. On the other hand, digital images analysis was performed to quantify the kinetics of the successive deterioration processes at stake and to express the corresponding kinematic and further strain and strain-rate fields.
