Summary

 
The paper presents and experimental study regarding the plastic deformation impact on the yield boundaries of the steels with yield strength of 280 ÷ 1200 MPa, which are plastically isotropic in their initial state. It examines single and cyclic loading and gives a relationship between the tangential modulus and preliminary plastic deformation of the reverse sign, as well as between η0 parameter and compression deformation. These data can be used to calculate non-elastic stability of beams and plates.
