Fracture at V-notches with contained plasticity

Engineering Fracture Mechanics, 2002
Abstract Fracture at V-notches with contained plasticity was studied. The tested material was a soft annealed tool steel, AISI O1, at −50°C. The material behaviour at this temperature was brittle for a standard fracture toughness test and ductile for a tensile test.

Influence of the V-Notch Opening Angle on Critical Applied Force Values for the Crack Initiation from the Sharp V-Notch

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.

Assessment of apex-V notches

2002
The singular stress field at the tip of an elastic sharp notch was reported by Atkinson et al. [12]. Kuang and Xu [72] presented the leading-order terms of the stress and strain fields under the J2 deformation plasticity theory for mode I plane strain cases.

The V-notched elastic half-plane problem

Acta Mechanica, 1979
The problem of a V-notched isotropic elastic half-plane under generalized plane stress or plane strain conditions can be reduced, by using the complex variable technique, to a complex Cauchy type singular integral equation along one of the V-notch edges. This equation can be numerically solved by use of the Gauss-Jacobi method and reduction to a system

Analysis of the Charpy V-notch test for welds

Engineering Fracture Mechanics, 2000
Abstract The ductile–brittle transition for a weld is investigated by numerical analyses of Charpy impact specimens. The material response is characterized by an elastic–viscoplastic constitutive relation for a porous plastic solid, with adiabatic heating due to plastic dissipation and the resulting thermal softening accounted for.

A fracture criterion for sharp V-notched samples

International Journal of Fracture, 2003
The objective of this paper is to show the advantages of the cohesivecrack model for predicting fracture of V-notched components. Criticalvalues of the generalized stress intensity factor can be obtained fromthe knowledge of the material softening function and the elastic parameters,avoiding a cumbersome experimental work.

The V-Notch Weir for Hot Water

Journal of Fluids Engineering, 1934
Abstract This ideally simple form of weir has a wide, accurate range for heads up to about one foot, is inherently free from aeration difficulties, and has a better agreement between data from various sources than would be expected from experience with other weir forms generally.

Vibration of Plates with Constrained V-Notches or Cracks

Journal of Engineering Mechanics, 2003
This paper reports the first known free vibration solutions for thin circular plates with V-notches having various edge conditions. The classical Ritz method is employed with 2 sets of admissible functions assumed for the transverse vibratory displacements.

Flow of Water Over a V-Notch

Transactions of the American Society of Mechanical Engineers, 1928
Abstract In this paper the author presents a formula for finding the flow of water over V-notches with angles ranging from 90 deg. down to 27 deg., which is based on the experimental results given in D. Robert Yarnall’s paper on the “Accuracy of the V-Notch-Weir Method of Measurement,” presented before the A.S.M.E. in December, 1926.
