Analytical Stress Intensity Factors for Cracks at Blunted V-notches
Procedia Materials Science, 2014 AbstractAn analytical expression for the Stress Intensity Factor (SIF) related to a crack emanating from a blunted V-notch root is put forward. Different notch amplitudes, ranging from 0° to 180°, and different crack length to root radius ratios, ranging from 0 to 10, are taken into account. The analysis is limited to mode I loading conditions, as long

On the extraction of notch stress intensity factors by the post-processing of stress data on the free edges of the notch [PDF]
The Journal of Strain Analysis for Engineering Design, 2000 Following on the lines of a previous paper dedicated to cracked components by Ciavarella et al., here the case of a notch of semi-angle α is considered. Contrary to the crack case (α = 180°), the free edges of the notch are easily accessible to experimental analysis; moreover they provide information about all the terms of the ...

Plastic Stress Intensity Factor for a V-Shaped Notch.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 2000 In the present study, the plastic singular stress occurring in a wedge is studied by using the finite element analysis. The results so obtained are in a good agreement with the results by the asymptotic analysis obtained by the authors previously. Based on the numerical results, the Kp of plastic stress intensity factor and the Kc of elastic stress ...

Damage accumulation near the cold-expanded hole due to high-cycle fatigue by crack compliance method
Fracture and Structural Integrity, 2021 The novel destructive method is implemented for quantitative assessment of fatigue damage accumulation in the stress concentration zone accompanied by residual stress due to cold expansion of the through-thickness hole. Damage accumulation is reached by
