Predicting fatigue crack growth rate in a welded butt joint: The role of effective R ratio in accounting for residual stress effect [PDF]

open access: yes, 2009
A simple and efficient method is presented in this paper for predicting fatigue crack growth rate in welded butt joints. Three well-known empirical crack growth laws are employed using the material constants that were obtained from the base material ...

Stress intensity factor solutions for CTS mixed mode specimen

open access: yesFracture and Structural Integrity, 2019
The Compact Tension Shear (CTS) specimen is used to study fracture and fatigue under mixed mode I/II loading conditions. The K solution available in literature was developed for fracture studies and does not consider the effect of crack deflection.

Development and analysis method of single element strain gage for stress intensity factor analysis in crack opening mode (Verification of analysis accuracy by simulated crack)

open access: yesNihon Kikai Gakkai ronbunshu, 2022
A dedicated strain gage has been developed to measure the stress intensity factor of cracks. Conventional strain gages dedicated to stress intensity factor analysis have been made by combining multiple elements into a single gage. Therefore, it took time

A novel weight function for RMS stress intensity factor determination in surface cracks [PDF]

open access: yes, 2010
This paper discusses the problem of stress intensity factor determination in surface cracks. In particular, the concept of root mean square stress intensity factors (RMS SIF) is discussed for the general class of semi-elliptical surface cracks.

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 Factor of Mode III Cracks in Thin Sheets

open access: yes, 2010
The stress field at the tip of a crack of a thin plate of elastic material that is broken due to a mode III shear tearing has a universal form with a non-universal amplitude, known as the stress intensity factor, which depends on the crack length and the
