TLDR
In this article, a general methodology is proposed for the determination of surface residual stresses and residual plastic strains using instrumented sharp indentation, which is assumed to be equibiaxial and uniform over a depth (beneath the indented surface) which is at least several times larger than the indentation contact diameter, and the indenter load and geometry can be so chosen as to minimize or maximize the contact radius to seek the broadest range of applicability and validity of the proposed method by recourse to macro-, micro- and nanoindentation of elastoplasticAbout:

Computational modeling of the forward and reverse problems in instrumented sharp indentation
TL;DR: In this article, a comprehensive computational study was undertaken to identify the extent to which elasto-plastic properties of ductile materials could be determined from instrumented sharp indentation and to quantify the sensitivity of such extracted properties to variations in the measured indentation data.

Nanoindentation studies of materials
TL;DR: Nanoindentation has become a commonplace tool for the measurement of mechanical properties at small scales, but may have even greater importance as a technique for experimental studies of fundamental materials physics as discussed by the authors.
