Assessing the elastic parameters and energy-dissipation capacity of solid materials: A residual indent may tell all

Acta Materialia

An analytical relationship between the ratio of hardness to reduced modulus H/E-r and the geometry of a residual indent is established based on the theories of depth-sensing indentation. Various material parameters, including elastic parameters, recovery deformation and energy-dissipation capacity, ...
