Review of Intermediate Strain Rate Testing Devices
Assuming that the sample is deformed at a constant strain rate, the maximum strain recorded is therefore ε max = ε̇ Δt, whereas Δt is the test duration and ε̇ is the strain rate. The test duration is rarely longer than 1 ms in conventional SHB. Therefore, at an average deformation rate of 100 s −1, the maximum strain measured is 10%.
