| Abstract: | A mathematical model is proposed for calculating the stress-strain state of a cylindrical specimen, which arises as a result
of plastic surface hardening leading to material deformation anisotropy. The model adequacy is verified through comparisons
with experimental data for cylindrical specimens made of 30KhGSA and St. 45 steels. A method of identifying model parameters on the basis of results of a fundamental experiment is developed. Good agreement
of the calculated and experimental data is demonstrated. |
