HIGH STRAIN RATE BEHAVIOR OF STEEL MATERIAL TYPICALLY USED IN ARMOUR APPLICATIONS

摘要

Materials behave differently when subjected to loads at different strain rates. The study of this field is very important in the analysis of the behavior and failure of components and structures that are subjected to dynamic loads. In the present work, the high strain rate behavior of steel used in armour applications has been investigated through tensile tests at low and medium strain rates and high rate compression tests in SHPB set up. The study shows that the material exhibits moderate strain rate sensitivity and is fairly constant over a wide range of strain rates.
