It has been established that for extrapolation of the functional dependence of true stresses for tensile conditions of cylindrical samples of metal materials in the region of large deformations, a power dependence is better suited, where the approximation parameters are uniquely determined by the standard mechanical characteristics of materials. A method is proposed for calculating the ultimate deformations during stretching of a sample under the simultaneous action of hydrostatic pressure. It is shown that the calculation results are in satisfactory agreement with the known experimental data obtained by P. Bridgman and J. Bell.
