Originální abstrakt

Hardness measurement is a common method of strain inhomogeneity evaluation, applicable regularly as a part of industrial forming processes analysis. The relation between measured hardness and strain is derived from so called strain-hardness reference curves, obtained usually by evaluation of compression tests for given material under relevant thermomechanical conditions. The procedure of reference curves evaluation is traditionally based on mean values of measured hardness and assumed homogeneous strain, obtained at each level of specimen compression. Using such “mean value” reference curves subsequently for local evaluation of strain in the industrial products can be questionable. With the help of numerical simulation of compression test, strain-hardness reference curve is constructed directly from local values. Reliability of the “mean value” reference curves can be thus quantified.
