The identification method of hardening parameters specifying stress - strain curve is proposed by applying spherical indentation test and measuring the penetration depth during loading and unloading. The loading program is composed of a geometric sequence of loading and partial unloading steps from which the variation of permanent penetration with load level is determined. This data is used for specification of two parameters k and m occurring in the plastic hardening curve E(p) = (T / k)(1/m), where E(p) denotes the plastic strain.
