TL;DR: This article showed that there can be multiple stress-strain curves for a given set of loading and unloading curves for elastic-plastic solids with work-hardening, and they showed that these curves can be uniquely determined from a conical or pyramidal indenter.
Abstract: Applying the scaling relationships developed recently for conical indentation in elastic-plastic solids with work-hardening, we examine the question of whether stress-strain relationships of such solids can be uniquely determined by matching the calculated loading and unloading curves with that measured experimentally. We show that there can be multiple stress-strain curves for a given set of loading and unloading curves. Consequently, stress-strain relationships may not be uniquely determined from loading and unloading curves alone using a conical or pyramidal indenter.

TL;DR: In this article, the scaling relationships for conical indentation into elastic-perfectly plastic solids were derived using dimensional analysis and finite element calculations, which provided new insights into the shape of indentation curves and formed the basis for understanding indentation measurements, including nano-and micro-indentation techniques.
