A continuum theory for elastic–plastic solids that accounts for the size-dependence of strain hardening is employed to analyze trends in the indentation hardness test. Strain gradient plasticity theory incorporates an elevation of .ow stress when non-uniform plastic deformations occur at the micron scale. Extensive experimental data exists for size… CONTINUE READING
