Abstract

Compressive deformation is imposed on aluminum cast 195-76 and ferritic stainless steel 18-8specimens at high strain rateusing perforation split Hopkinson pressure bar (P-SHPB).The energy levels and the compressive dynamic failure behavior of the materials were investigated at high strain rate deformation between 950 and 5700 s-1. This paper investigates the effects of specimen’s thickness andimpact energy on failure behavior with correlation of P-SHPB and SHPB.The relationship of different damage mode can be followed with the stress-strain relationship, strain rate and energy absorbed by steel and aluminum specimens.
