Abstract
The elastic aftereffect and stress relaxation after testing in stable and metastable
sheet steels of different structural classes subjected to monotonic and alternating loading under
various conditions have been studied. Dependence of the material mechanical behavior and
distribution of residual stresses on the strength, possibilities of phase transformations
under load and sequence of alternating loading have been shown. A mathematical model for
stamping test of sheet steels taking into account phase transformations and stress relaxation
has been developed.
