Dynamic tensile strength enhancement of concrete in split Hopkinson pressure bar test
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.

Wave Dispersion and Attenuation in Viscoelastic Split Hopkinson Pressure Bar
A viscoelastic split Hopkinson pressure bar intended for testing soft materials with low acoustic impedance is studied. Using one-dimensional linear viscoelastic wave propagation theory, the basic equations have been established for the determination of ...

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

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

Behavior of high-density polyethylene at high strain rates
The Hopkinson split pressure bar (HSPB) was used for the testing of three polymers at strain rates between 10^2 to 10^3 1/s. Higher strain rates were achieved using the direct Hopkinson test.
