| Popis: | The work is devoted to the experimental study of steels and alloys deformation properties with account to the mutual influence of the cyclic and static deformation components. Carbon steel and three different chrome-nickel austenitic steels were tested at different temperatures and durations. At strain-controlled cyclic loading these steels demonstrate cyclic hardening (or softening – depending on the previous history) at the running-in stage, then stabilization and subsequent softening at the pre-fracture stage. Experiments show that in case of comparable cyclic and static damage the mutual influence of the cyclic and static material hardening (softening) strongly affects the stress-strain diagrams; this effect should be taken into account in structural analysis. Models that use only the information about static or strain-controlled cyclic loading are incapable to describe this effect. |
