Near-threshold Fatigue Crack Propagation under Mixed-mode II+III in ARMCO Iron
Original language description
The paper is dedicated to experiments on near-threshold fatigue cracks under mixed-mode II+III in the ARMCO iron. The aim is to find the intrinsic (effective) threshold value of stress intensity factor (SIF) range in the mixed mode II+III and to compareit to those in modes II, III as well as to elucidate the crack growth mechanism. In this paper we only focus on the mixed-mode II+III experiment. Cylindrical bars with circumferential cracked notch were loaded by shear force. The notch is located in themiddle of the bar and, therefore, no bending moment is present. Pre-cracks were created by compressive cyclic loading in mode I to obtain smooth fracture surfaces. After the experiment, the specimens were fractured under very low temperature or by cyclictensile loading. The circumferential crack was loaded by different combination of modes II and III. The SIFs in mode II and III were numerically calculated using FEM. Two simple formulae were used to evaluate the effective mixed-mode SIF
