  • Hardness - Wikipedia

    Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion Some materials (eg metals) are harder than others (eg plastics, wood)Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness .
