Brittle fracture in rounded-tip V-shaped notches
TLDR
In this article, two failure criteria are proposed for brittle fracture in rounded-tip V-shaped notches under pure mode I loading, one of these criteria is developed based on the mean stress criterion and the other based on point stress criterion.About:

Recent developments in brittle and quasi-brittle failure assessment of engineering materials by means of local approaches
Filippo Berto,Paolo Lazzarin +1 more
TL;DR: In this article, the authors present a review of some local approaches applicable near stress raisers both sharp and blunt V-notches, which has been recently applied to assess the brittle failure of a large number of materials.

An improved semi-circular bend specimen for investigating mixed mode brittle fracture
TL;DR: In this article, an edge cracked semi-circular specimen subjected to asymmetric three-point bend loading was suggested for investigating mixed mode fracture in brittle materials using finite element analysis, the crack parameters were obtained for various crack lengths and different locations of loading points.

Determination of mode III fracture toughness for different materials using a new designed test configuration
TL;DR: In this article, the Edge Notched Disc Bend (ENDB) is proposed for experimental determination of KIIIc, which is a circular disc containing an edge crack created along the disc diameter which is subjected to three-point bend loading.

Tensile fracture in notched polycrystalline graphite specimens
TL;DR: In this article, a fracture theory was developed to determine the notch fracture toughness and experimental results agreed well with the theory and three different geometric notch shapes were investigated, including V-notches.

Brittle fracture of U-notched graphite plates under mixed mode loading
TL;DR: In this paper, the average value of the strain energy density over a control volume is used to assess the static strength of the specimens subjected to different mode mixities and the volume size depends on the fracture toughness and the ultimate tensile strength.

Stress Singularities Resulting From Various Boundary Conditions in Angular Corners of Plates in Extension
TL;DR: In this paper, the authors investigated three boundary conditions on the radial edges: free-free, clamped-clamped, and clamped free, and showed that the free free extensional plate behaves locally at the origin exactly the same as a clampedclamped plate in bending, independent of Poisson's ratio.

A finite-volume-energy based approach to predict the static and fatigue behavior of components with sharp V-shaped notches
Paolo Lazzarin,R. Zambardi +1 more
TL;DR: In this article, an energetic approach is proposed to predict the static and fatigue behavior of components weakened by sharp reentrant corners, where the energy in a small volume of material surrounding the notch tip has a finite value and such a value is thought of as the entity that controls the failure.

Brittle fracture criterion for structures with sharp notches
TL;DR: In this paper, a brittle fracture criterion for structures with sharp notches is proposed based on Irwin's and Novozhilov's criteria and states that a crack will propagate from a tip of a notch when the actual value of the stress intensity factor KI,II,III reaches a critical value.
