THE CALCULATION OF STRESS INTENSITY FACTOR STEEL OF RAILWAY WHEELS [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2020
From an analysis of the dependence complex of carbon steel properties on structural parameters, it was found that for an isostructural state, the influence of austenite grain size on impact strength exceeds the dependence on carbon content.

Stress Intensity Factors Evaluated from Discontinuous Displacements along a Slant Crack with a Center-Hole Notch

open access: yes, 1995
For cracks with a center-hole notch under the mixed-mode condition, a method is proposed in which the stress intensity factor can be directly evaluated from the discontinuous crack displacement, thus representing effective stress intensity factors. Using
