Direct method of solving the boundary-value problem of relaxation of residual stresses in a hardened cylindrical specimen under creep conditions
V. P. Radchenko, M. N. Saushkin Samara State Technical University, Samara, 443100, Russia
Abstract:
A direct method of solving a boundary-value problem for a surface-hardened cylindrical specimen affected by a tensile load under creep conditions is proposed. Relations for estimating the kinetics of the stress-strain state in the hardened layer are obtained. The adequacy of the solution is verified by experimental data on relaxation of residual stresses in the hardened layer of a cylindrical specimen made of ÉI 691 steel at $T=400^\circ$C. The calculated and experimental residual stresses are demonstrated to be in good agreement.
Keywords:
cylindrical specimen, plastic surface hardening, residual stresses, creep, relaxation.
