In-Situ Measurement of Mechanical Properties using Automated Ball Indentation Technique

Abstract

To assess the health/integrity of critical engineering component, evaluation of mechanical properties of the material from which the component is made is essential. Estimation of mechanical properties through conventional route is well established and standardized, but in-situ measurement on original structure or by using small amount of materials are in demand and yet to be standardized. As conventional mechanical test requires an adequate amount of test materials and in most of the cases this may not be available from the components that are in service. There-fore, an approach to find the mechanical properties either in-situ or using small amount of test materials got utter importance as an area of research for quite some time.
