Abstract

We propose a computational and experimental procedure for the investigation of the influence of thermomechanical loading on the propagation of a corner fatigue crack under cyclic loading. The taring dependence of the stress intensity factor on the relative radius of the crack is plotted. The limited kinetic diagrams are presented for KhN73MBTYu (ÉI698VD) high-temperature chromiumnickel alloy for temperatures of 20 and 600°C.
