| Abstract [eng] |
After the investigation of 227 structural materials at low cycle straining, the cycle properties of structural materials by mechanical characteristics were evaluated. After a thorough analysis of the graphical results, the cyclic stress-strain curves parameter α, which characterizes intensity of cyclic hardening or softening of structural materials at room and elevated temperature rather precisely, was determined. Dependences for the evaluation of cyclic instability according to modified plasticity (ɕu/ɕy)Z at room and elevated temperature for structural steels and their weld metal were specified. |
