An inverse problem of identification of the elastoplastic properties of power hardening engineering materials from limited spherical indentation measurements is studied. A fast algorithm for reconstruction of the Ramberg-Osgood curve sigma(i) = sigma(0)(e(i)/e(0))(kappa), with the strain hardening exponent kappa is an element of (0, 1), is proposed. The main distinguished feature of this algorithm is that the only two output measured data
