БАГАТОВІСНА ВТОМА ТИТАНОВИХ СПЛАВІВ ТА ЕФЕКТИ НЕПРОПОРЦІЙНОСТІ НАВАНТАЖУВАННЯ

М. М. Гладський

Abstract


The effect of additional cyclic hardening under regular loading was investigated based on experimental results of BT1-0 and BT9 titanium alloys. Load non-proportionality had no effect on deformation behavior and cyclic stress–strain data were correlated by von Mises equivalent criterion. The Fatemi–Socie critical plane approach was found to correlate in-phase and out-of-phase experimental data of both titanium alloys very well.
