Stress Intensity Factors for Notched Configurations

Journal of Testing and Evaluation, 1985
Abstract A method is presented for approximating stress intensity factors for notched-configurations without cracks. It is expected that estimates obtained from such analyses, which are outlined in the text and detailed in the Appendix, should be useful in estimating the failure load in a notched structure behaving in an idealized ...

THE STRESS INTENSITY FACTOR OF SMALL CRACKS AT NOTCHES

Fatigue & Fracture of Engineering Materials & Structures, 1982
Abstract— It was found in a previous publication that stress fields around notches are quantitatively very similar, if the peak stress at the notch root (σpeak) and the notch root radius (ρ) are the same. As a consequence, small cracks (length l) should have the same stress intensity factor, if σpeak and ρ are similar.

Stress Intensity Factors for Single‐Edge‐Notch Beam

Journal of Engineering Mechanics, 1984
The Strawley equations are commonly used to determine the stress-intensity value for a single-edge-notch beam subjected to three-point, four-point, or pure bending. These equations were derived using assumptions treating the concentrated loads that limited the results to certain ranges of span to depth.

An influence function for stress intensity factors of bimaterial notched bodies

International Journal of Fracture, 1997
The problem of a notch at a bimaterial interface is considered. An influence function is developed for determining the stress intensity factors for all notch angles in infinite bodies. Particular solutions are obtained for cracks in homogeneous and bimaterial bodies and for bonded strips. Comparison with solutions in the literature is excellent.

A simple approximation for the stress intensity factor of a crack at a notch

The Journal of Strain Analysis for Engineering Design, 1991
A simple procedure for estimating the stress intensity factor of a continuous crack at the root of a circumferential notch in a round bar is presented. Numerical solutions for equivalent notched and un-notched geometries are compared. The resulting correction term for notches is formulated as a polynomial equation using only notch geometric parameters ...

Stress Intensity Factor Interaction of Subsurface Flaws Under Notches

Volume 1A: Codes and Standards, 2017
If a single subsurface flaw is detected that is close to the component free surface, a flaw-to-surface proximity rule is used to determine whether the flaw should be treated as a subsurface flaw, or transformed to a surface flaw. The transformation from subsurface to surface flaw is adopted as flaw-to-surface proximity rules in all fitness-for-service (

Stress Intensity Factor Calibration of Edge-Notched Beam

1997
Several solutions necessary to determine the mixed-mode stress intensity factors in edge-notched plane stress beams subject to a wide variety of loading conditions are given. These solutions include stress intensity factors in an edge-notched beam subject to: (1) pure moment, (2) pure shear, (3) a point load at the bottom of the beam in the vicinity of

ESTIMATIONS OF STRESS INTENSITY FACTORS FOR SMALL CRACKS AT NOTCHES

Fatigue & Fracture of Engineering Materials & Structures, 1991
AbstractThis paper presents a simple method for determining the stress intensity factors for small notch‐emanating cracks. The proposed method is based on similarities between elastic notch‐tip stress fields described by two parameters; the stress concentration factor K1, and the notch‐tip radius ρ.

Fatigue and fracture emanating from notch; the use of the notch stress intensity factor

Nuclear Engineering and Design, 1998
Abstract The analysis of the stress distribution at notch tip shows a pseudo-stress singularity characterised by the notch stress intensity factor (NSIF) Kρ. The critical value of this parameter Kρccan be used to determine the fracture toughness of very brittle materials from notched specimens. The range of the notch stress intensity factor ΔKρ plays
