Abstract
A new technique for testing dynamic spherical indentation of materials was proposed. It is implement by putting a WC alloy ball between two specimens. One of the specimens was bonded with input bar and the other was bonded with the output bar. Two specimens then was pressed in the process of indentation. This simple arrangement can accomplish a very accurate measurement of force and displacement during the indentation. A FEA simulation has been carried out using ABAQUS/explicit to evaluation this new technique. The dynamic indentation test of 7075-T4 aluminum alloy was conducted. The simulation and experiment result show the new method gives a more accurate results compare to other dynamic indent experimental method.
