Abstract
Results of experimental investigations at the room temperature of specimens made from steel 3 are presented in a paper. It was found, that steel 3 at room temperature demonstrates essential creep, when strains are more than 2%. The anisotropy of creep properties for considered steel was fixed. The values of constants which are included in suggested state equations for steel 3 at temperature 20 С were determined. Comparison between experimental and calculated data show the satisfactory ability of use the suggested state equations for numerical simulation of stress-strain state’s varying in conditions, when load causes the instant stresses which are more than yield limit as well as instant plastic strains occur.
