Abstract
An experimental technique based on elastic stress wave propagation phenomena in a slender rod is utilized for determining the dynamic Vickers indentation hardness in metals. Dynamic Vickers hardness (DVH) for several engineering metals is found to be greater than their static Vickers hardness (VH). The results were verified by obtaining the constitutive response of materials at similar strain rates and then correlating the yield stress with the corresponding hardness. The characteristics of the induced plastic zone under static and dynamic indentations were investigated by contouring microindentation hardness measurements and microstructural analysis of the deformed regions. The studies revealed that the size of the plastic zone is strongly a function of yield stress under static and dynamic conditions. © 1999 Published by Elsevier Science S.A. All rights reserved.
