Microindentation Mapping With Acoustic Emission On Glass

Microindentation hardness mapping has been widely used to assess the variation of mechanical properties across a large surface area. However, with the study of applications such as glass it is the crack initiation that is of particular interest. It is for this reason that acoustic emission can be used during the mapping of indents to not only map hardness but also map the crack initiation values over the surface area. Using acoustic emission proves to be a critical tool during the study of applications where micro fracture is of primary concern.
