Abstract
The measurement accuracy in dynamic tension testing is required for the development of design and numerical simulation based on the accurate model of stress-strain relation which is applicable to various strain-rate conditions. The Hopkinson bar method (HBM) is the most widely used one for the dynamic compression test, whereas this method is not used very much for the dynamic tension test. The non-coaxial Hopkinson bar method (NCHBM) is one of the recently proposed dynamic tension tests and is based on HBM. In this study, the accuracy of the stress-strain relation obtained on the basis of NCHBM was discussed by using the FEM code LS-DYNA and by experiment, for SUS316 stainless steel.
