Portable Low-Impact Surface Hardness Testing of Mineral Materials: An Integrative Review of Applications, Interpretation, and Methodological Considerations

Abstract This integrative review critically examines portable dynamic low-impact surface hardness (LISH) testing, also known as Leeb hardness. Since its adaptation for mineral materials in 1993, LISH has been increasingly adopted across geoscience, engineering, and heritage conse...
