under the effect of elastic force, and calculate the hardness value with the ratio of the
rebound speed and impact speed of the punch at a distance of 1mm from the sample
surface. The calculation formula is as follows:
HL=1000 * VB/VA
Where: HL - Leeb hardness value
VB -- Rebound speed of impact body
VA - Impact velocity of impact body
The output signal of the impact device is shown in the following diagram:
