AbstractThis paper aims to obtain an analytical expression for the ratio of unloading work of indentation (W-u) to total loading work of indentation (W-t) (work recovery ratio of indentation) in instrumented spherical indentation. The expanding cavity model and Lame solution are used. Three typical stress-strain relations (elastic-perfectly plastic, linear hardening, and power-law hardening) are analyzed. The results of finite-element method coincide with the expressions. The expressions show that the work recovery ratio of indentation is just related to plastic parameters. Furthermore, elastic work (W-e) are obtained, and it is proved that W-e should be distinguished from W-u in spherical indentation.
