Dynamic tensile strength enhancement of concrete in split Hopkinson pressure bar test
Advances in Mechanical Engineering, 2018 Split Hopkinson pressure bar technique has been widely used to measure the dynamic tensile strength of concrete materials. Most experimental results show that the tensile strength of concrete material increases with strain rates.

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

Size Effect in the Split Hopkinson Pressure Bar Experiment
Journal 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]
한국정밀공학회지In 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]
, 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 ...
