Abstract
WHEN a piece of metal has been subjected to local plastic deformation, as, for example, by indentation, it is important in research work to be able to determine the distribution of strain and the elastic–plastic boundary. At least five methods are available for these determinations, and Williams and O'Neill1 recently published results using explorations by low-load hardness tests. Samuels and Mulhearn2 have pointed out the defects of some of the existing methods.
