low energy impact testers

Charpy Test - Determination of Impact Energy Using , low energy impact testers ,Impact energy is a measure of the work done to fracture a test specimen When the striker impacts the specimen, the specimen will absorb energy until it yields At this point, the specimen will begin to undergo plastic deformation at the notch The test specimen continues to absorb energy and work .Low energy impact on the interface of bamboo-steel ,May 31, 2018·,32;Low-energy impact tests were performed on a drop-weight impact test machine CEAST 9350 manufactured by INSTRON and the data acquisition rate was set at 4 MHz The specimens were fully clamped except the impact area.
