Research Abstract |
Rocks consist of parts with various mechanical hardnesses. I propose in this study a technique of mechanical mapping to reveal a distribution of harder parts and softer parts within a well-polished surface of rocks with a depth-sensing nano-indentation tester. Introduction of an active damper to nano-indentation technique is very effective to reduce irregularity for measuring the depth of indentation due to tremor. I emphasise in this study that the loop energy and the depth of indentation are the most fundamental data for further analysis of mechanical mapping.
