LLNL small-scale drop-hammer impact sensitivity test [PDF]

open access: yes, 1995
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 ...

Effect of Impact Load on Splice Length of Reinforcing Bars

open access: yesInternational Journal of Concrete Structures and Materials, 2020
Impact loading damage of reinforced concrete (RC) members deteriorates bond strength of reinforcing bars. To understand the effect of strain rate on the bond strength of reinforcing bars in RC beams under impact load, drop hammer test was performed on ...

Crack Detection in an Aluminium Oxide Grinding Wheel by Impact Hammer Tests

open access: yesComputation, 2023
Grinding is widely used as the last step of the manufacturing process when a good surface finish and precise dimensional tolerances are required. However, if the grinding wheels have cracks, they may lead to a hazardous working environment and produce ...

Simulation Model and Case Study of Drainage Process After Pressure Test of Large Drop Natural Gas Pipeline

open access: yesIEEE Access, 2020
The drainage process of a large drop natural gas pipeline after a pressure test is a complicated transient flow process. This process is a gas-phase and liquid-phase flow process connected by a pig, in which the pressure inside the tube, and the flow ...

On an Impact Testing Machine of Drop Hammer Type

open access: yesjournal of the Japan Society for Testing Materials, 1961
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
