Abstract [eng] The results, received in KTU Department of Machine Design laboratory in 1970-2000, of 75 weld metals of alloyed structural steels at room temperature and 40 welded joints at elevated temperature were analyzed in this paper. The results of the materials were additionally divided in to Cr-Ni, Cr-Ni-Mo, Cr-Ni-Mo-V groups. The proportionality limit stress and the parameters and of cyclic stress-stain curves linear dependences on the modified plasticity criterion for separated groups of weld metals of alloyed structural steels were investigated. Analytical dependences of cyclic stress-strain parameters on the modified plasticity criterion for Cr-Ni, Cr-Ni-Mo, Cr-Ni-Mo-V welded joints are proposed at room and elevated temperatures. The comparison of cyclic stress-strain curves calculated and experimental characteristics results showed that additional grouping of the materials by the chemical composition has influence while defining the parameters by the modified plasticity criterion at room and elevated temperatures.
