A new method for estimating residual stresses by instrumented sharp indentation
TL;DR: 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 elastoplastic
