Dynamic Tensile Testing of Structural Materials Using a Split Hopkinson Bar Apparatus

Abstract

Stress-strain curves in tension obtained on a large number of structural materials at strain rates up to 1000/s are presented. A modified split Hopkinson bar apparatus used for high strain rate tensile testing is described. Data are compared with other published results. The flow stress of all the materials tested is seen to increase to some extent over the range in strain rates from 0.001 to 1000/s.
