The emerging trend is to go beyond traditional risk-based inspection (RBI) to knowledge based inspection (KBI) which aims to understand mechanisms and use information to schedule the next inspection, represented by the dotted line in the bath tub curve. The benefit of this approach is an increase in plant availability factor as well as extended operational life beyond design limits.
AMIT (automated macro indentation test) falls in the category of knowledge-based inspection system.
What is AMIT ?
AMIT, automated macro indentation test, is a technique used for in-situ determination of key mechanical properties of components, such as yield strength (YS), ultimate tensile strength (UTS), strain hardening exponent (n), hardness (BHN) and fracture toughness (KIC). This technique was jointly developed by Ducom Instruments in partnership with NML, Jamshedpur.
