A Dynamic Microindentation Apparatus for Materials Characterization

CODEN: JTEVAB

Abstract

A microindentation system is described that provides a new approach to dynamic mechanical testing. The indentation is characterized in terms of continuous measurements of applied load and penetration depth. The indentation can be performed over a wide range of loading times from hours to milliseconds. The shape of the loading waveform can also be selected. The deformation energy can be measured and partitioned into elastic, plastic, and anelastic components. The apparatus is also able to perform conventional hardness testing, and may be useful for estimating conventional mechanical properties.
