Extended Stress–Strain Characterization of Automotive Steels at Dynamic Rates
Demanding structural applications require a detailed knowledge of the materials response up to the very late stages before failure. Ductile high-strength steels may undergo pronounced necking over the majority of their straining life; this makes a ...
