The material porosity values in the circular cross-section sample before the neck, and after the occurrence of the neck at different points of the smallest cross-section of the neck are obtained. The numerical data show that the dangerous point of the sample is in the center of the smallest cross-section of the neck, at which the sample's destruction starts. The obtained results are compared with the available experimental data, the porosity of the sample after its deformation is determined.
