Abstract

The axisymmetric specimen applied in the tensile test is numerically characterised within this chapter. Subsequently, the simplifying assumptions of the classical approaches are verified utilising the results obtained from the numerical simulation and the errors were determined. These investigations can clarify the influence of each particular simplification on the value of the average normalised axial stress in the minimum section plane. Additionally, the errors were estimated which follow from the application of the formula for the true (logarithmic) plastic strain instead of the strain intensity in the flow curve. However, the highest significance, from the point of view of application of particular formulae, had the estimation of the errors created by application of the classical and newly derived formulae to determine the flow curve from the moment of neck formation.
