A Laboratory-Scale Instrumented Forging Hammer as an Intermediate Strain Rate Testing Device [PDF]
Mechanical characterisation of metallic materials at intermediate strain rates is essential to calibrate and validate computational models for industrial applications such as high-speed forming processes i.e. hammer forging, blanking, forming, etc.

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.
