... experimental data available in literature. Introduction In common practice of rock engineering, the Schmidt hammer is widely used to obtain an indirect estimation of the intact rock strength, specifically of its uniaxial compressive strength (UCS) [1–4]. UCS can be easily calculated by means of empirical...
