Abstract

Abstract

A new technique for testing dynamic spherical indentation of materials was proposed.It was implemented by putting a WC alloy ball between two specimens, one of which was bonded with the input bar and the other was bonded with the output bar.Then the two speciemens were pressed in the process of indentation.With this simple arrangement we can accomplish a very accurate measurment of force and displacement during the indentation.A finite element simulation was carried out by using the ABAQUS/Explicit software to evaluate this new experimental technique.The results show that the new method gives a more accurate result than other dynamic indent experimental methods.In addition, by testing the alumimum alloy materials, the curves of the indentation force and depth were gotten based on the new technique.The investigation diaplays that the technique proposed can porvide more accuate results and refect the indentation process more truely.
