Numerical Modeling of a Split Hopkinson Pressure Bar Test

open access: yesEuropean 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 ...

Two-wave photon Doppler velocimetry measurements in direct impact Hopkinson pressure bar experiments

open access: yesEPJ Web of Conferences, 2015
Direct impact Hopkinson pressure bar systems offer many potential advantages over split Hopkinson pressure bars, including access to higher strain rates, higher strains for equivalent striker velocity and system length, lower dispersion and faster ...

Stress Equilibrium in the Split Hopkinson Pressure Bar Test [PDF]

open access: yesLe 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

Size Effect in the Split Hopkinson Pressure Bar Experiment

open access: yesJournal of Physics: Conference Series, 2022
Abstract For many structures, their service environment is very strict, and the requirements for the impact resistance of materials are very high. Therefore, the dynamic testing method has important scientific significance and application value for practical engineering.

A Numerical Investigation of Deformed Region in Plate Specimen of Split-Hopkinson Tensile Bar [PDF]

open access: yes한국정밀공학회지
In Hopkinson bar theory, stress, strain, and strain rate can be determined by analyzing the dimensions of the specimen. When conducting Split-Hopkinson Pressure Bar (SHPB) experiments, the stress-strain curve is obtained by considering the entire length ...

New experimental techniques with the split Hopkinson pressure bar [PDF]

open access: yes, 1984
The split Hopkinson pressure bar or Kolsky bar has provided for many years a technique for performing compression tests at strain rates approaching 10/sup 4/ s/sup -1/. At these strain rates, the small dimensions possible in a compression test specimen give an advantage over a dynamic tensile test by allowing the stress within the specimen to ...
