Numerical Modeling of a Split Hopkinson Pressure Bar Test
European Journal of Engineering and Technology Research, 2021 In this work, a one-dimensional simplified model was developed to predict stress, strain, and strain-rate in high strain rates Hopkinson pressure bar experiments, namely, between 500-5000/s. To this goal, a one-dimensional model for Hokinson bar tests was developed based on analyses of wave propagation in bars and assuming the specimen is under ...

Stress Equilibrium in the Split Hopkinson Pressure Bar Test [PDF]
Le Journal de Physique IV, 1997 The compressive split Hopkinson pressure bar (SHPB) technique allows the stresses on each end of the specimen to be measured individually. Results are presented showing a large difference between these end pressures, depending on specimen length and loading rate. The mechanisms responsible are show to be a combination of inertial forces and non-uniform
