Determination of Johnson-Cook constitutive model coefficients considering initial gap between contact faces in SHPB test
When a material is deformed at high speed, it is well known that the flow stress is highly dependent on the strain rate and temperature. So, many studies of the stress-strain relationship at high strain rate condition have been conducted using the Split Hopkinson Pressure Bar (SHPB) test. Studies ab...
