A general weight function for inclined cracks at sharp V-notches
Engineering Fracture Mechanics, 2007Abstract A general method for evaluating the Stress Intensity Factors of an inclined edge crack originated at the tip of a sharp V -notch in a semiplane is presented. An analytical Weight Function with a matrix structure was derived by extending a method developed for an inclined edge crack in an unnotched semi-plane.

Sharp V-Notches Subjected to Axial and Shear Stresses
1990In the last few years, stress field criteria, similar to those used in linear elastic fracture mechanics, have been proposed for fatigue design of structures with sharp V-notches under symmetrical (pure tension) or anti-symmetrical (pure shear) conditions. For the case of combined conditions, an analytical study has recently been performed.

Key Engineering Materials, 2014
The aim of this paper is to estimate a value of the critical applied force for a crack initiation from the sharp V-notch tip. The classical approach of the linear elastic fracture mechanics (LELM) was generalized, because the stress singularity exponent differs from 0.5 in studied case.

NSIFs of 2D elastic bodies with straight and curved sharp V-notches
AIP Conference Proceedings, 2019In this work, a recently proposed technique: The point substitution displacement technique (PSDT) is extended to compute the accurate mode I notch stress intensity factors (NSIFs) of elastic bodies with straight and curve sharp V- notches. Certain optimal points on the notch flanks are identified using a least-squares technique where the displacements ...

Singularities at the apex of a sharp V-notch in a linear strain hardening material
International Journal of Fracture, 1992The strength of the stress singularities at the apex of a sharp V-notch for plane problems are investigated analytically in this paper. Three sets of boundary conditions, namely, free-free, fixed-fixed, and fixed-free, along the two faces of the notch are considered.

Influence of nozzle sharpness on the flow fields of V-notched nozzle jets
Physics of Fluids, 2009This study reports on an experimental investigation on laminar jets discharging from V-notched nozzles of different relative sharpness. Each nozzle consists of two smooth peaks and two sharp troughs and its sharpness is defined by the aspect ratio (AR) of the half ellipses which make up each half of the V-notch.

Three dimensional flow simulation over a sharp-crested V-Notch weir
Flow Measurement and Instrumentation, 2020Abstract Thin-plate weirs are widely used to monitor the flow rate in open channels. Thereby, three dimensional (3D) modeling of the flow over a weir in an open channel can be considered as one of the main topics in hydraulic science. In this study, the flow over a sharp-crested v-notch weir (SCVW) is simulated by a 3D numerical model.

Brittle fracture of sharp and blunt V-notches in isostatic graphite under torsion loading
Carbon, 2012Abstract Brittle fracture of polycrystalline graphite under torsion loading is studied experimentally and theoretically using axisymmetric specimens weakened by sharp and rounded-tip V-notches. The main purpose is twofold. First, to provide a new set of experimental data from notched samples made of isostatic polycrystalline graphite with different ...

SIFs evaluation of sharp V-notched fracture by XFEM and strain energy approach
Theoretical and Applied Fracture Mechanics, 2017Abstract Numerical estimation of stress intensity factors (SIFs), an important fracture mechanics parameter, for sharp V-notched structures is presented by using a new effective approach based on strain energy method associated with extended finite element method (XFEM). This approach takes advantages of both enrichments and the strain energy method.
