Summary
In-situ micromechanics is a new developed advanced technology and significantly supports the understanding of materials insights under micro-nano scale. However, it has been mainly used by materials community to characterise the mechanical properties of new materials while rarely used by the manufacturing community to support the manufacturing technology development.
University of Nottingham, with its closed partnership with micromechanics industry, has been conducting significant research in this area. This talk gives a brief introduction of the recent advancements in the research of in-situ micromechanics application in manufacturing processes at the university of Nottingham. It will cover two aspects: (i) understanding the phenomena occurring in the workpiece (sub) surfaces after manufacturing operation by performing very high resolution micro-mechanical testing (e.g. compression/bending of micro-pillars/beams); (ii) studying the material removal mechanisms at micrometric level using common indenters or dedicated edges to understand how the workpiece materials (e.g. groups/single grains) react to cutting conditions.
