LLNL small-scale drop-hammer impact sensitivity test [PDF]
Small-scale safety testing of explosives and other energetic materials is done to determine their sensitivity to various stimuli including friction, static spark, and impact. This testing is typically done to discover potential handling problems for either newly synthesized materials of unknown behavior or materials that have been stored for long ...

On an Impact Testing Machine of Drop Hammer Type
In order to research on the behaviors of destruction of carbon steel forgings by impact bending, we designed an impact testing machine of drop hammer type. The total height of this testing machine is about 5m. The weights of the used drop hammers are 12.5, 25 and 50kg respectively. The maximum distance from the position of test piece to the drop hammer

Estimation of Impact Hardness of Rocks by Means of Drop Hammer Test.
The impact hardness of rock is normally determined by using a ‘Protodyakonov’ type drop hammer. However, this test cannot be applied to a wide range of rocks. Therefore, standardized impact hardness test using the ‘Protodyakonov’ type drop hammer was carried out and the correlati ons of the resulting values of impact hardness with the mechanical ...
