Des theories basées sur l'energie de rupture d' ecaillage sont examinées. L'influence de la structure est etudiée. La transition fracture est examinée.
The spall behaviour of low alloyed high strength steel was studied. Nine different microstructures of this steel were prepared. The experimentally found dependence of spall strength, σc, on the strain rate, ε., exhibited features suggesting a transition in the spall fracture mode. The results were interpreted in terms of an energy-based theory of spall.
