Determination of stress intensity factors from stress concentrations for V-notched beams
Engineering Fracture Mechanics, 1987Abstract The calculation of stress intensity factor for a sharp V-notch is done from the limiting value of stress concentration factors as the root radius of the same V-notch rounded at the tip approaches zero. The stress analysis is carried out using the complex variable formulation of Muskhelishvili and the conformal mapping technique.

Creep Notch Stress Intensity Factors for Mode 1 Loaded Solids with Pointed V Notches
Engineering Fracture MechanicsIn the present work, a method to derive the creep Notch Stress Intensity Factors (NSIFs), quantifying the intensity of the stress fields in V-notched creeping solids, is proposed. The method is based on a non-conventional reformulation of the well-known Neuber Rule, focusing the attention on Mode 1 loaded V-notched solids under plane strain conditions ...

The method of singular integral equations is used to find the solution of the plane problem of the theory of elasticity for a plane containing an infinite V-shaped rounded notch. This enables us to establish the relationship between the stress intensity factor at the tip of the sharp V-shaped notch, the stress concentration factor for the corresponding

Plastic notch stress intensity factors for large V-shaped notches under mixed load conditions
International Journal of Fracture, 2001The paper presents a two-terms asymptotic analysis of the near-tip stress fields of sharp V-shaped notches having the bisector inclined with respect to remotely applied tensile stress. Due to their geometry, mixed-load conditions are present at the notch tip. The governing of equations result in a leading order system and a second order system.

Stress intensity factors for cracks at the vertex of a rounded V-notch
Materials Science, 2009The method of singular integral equations was applied to determine the stress intensity factors for a system of cracks emanating from the vertex of an infinite rounded V-notch subjected to symmetric loading. The numerical values were obtained for two cases—the case of a single crack and the case of a system of two cracks of equal length.

Stress Intensity Factors for Hollow Circumferentially Notched Round Bars
Journal of Basic Engineering, 1967Stress intensity factors are presented for a hollow circumferentially notched round bar subjected to tension, torsion, bending, and transverse shear. These previously undetermined factors are calculated from the limiting values of stress concentration factors for a small notch root radius. The stress intensity factors obtained are compared with results
