M.E. Kipp,G.C. Sih +1 more
TLDR
In this paper, the authors apply the strain energy density failure criterion to plane notch problems, where the crack now becomes a special case of a more generalized approach to failure, and the specific case considered is that of the plane elliptical cavity under remote tension and compression.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.

A review of the volume-based strain energy density approach applied to V-notches and welded structures
Filippo Berto,Paolo Lazzarin +1 more
TL;DR: In this paper, a large bulk of experimental data from static tests of sharp and blunt V-notches and from fatigue tests of welded joints are presented in an unified way by using the mean value of the Strain Energy Density (SED) over a given finite-size volume surrounding the highly stressed regions.

Fracture testing of a soft rock with semi-circular specimens under three-point bending. Part 2—mixed-mode
TL;DR: In this article, a semi-circular specimen under three-point bending (SCB) technique was employed to determine the Mode I fracture toughness of a water-saturated synthetic mudstone.

On the maximum strain criterion—a new approach to the angled crack problem
TL;DR: In this article, the maximum normal-strain theory for fracture is modified as a new approach to the study of the angled crack problem, and the authors present predictions on the direction of initial crack extension and the fracture strength for plates containing a slit crack as well as those with an elliptic crack under uniform edge stresses.
Journal ArticleDOI
Finite element models for rock fracture mechanics
TL;DR: In this article, a finite element model for the prediction of discrete fracture propagation in rock structures loaded in compression is presented, which integrates any one of three theories for mixed-mode fracture initiation; it contains an energy balance algorithm for predicting crack increment length.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.

Fracture under complex stress — The angled crack problem
J. G. Williams,P. D. Ewing +1 more
TL;DR: In this paper, the authors used a critical stress at a critical distance interpretation of the stress intensity factor criterion to improve the correlation between linear theory and experiment, using the critical stress component parallel to the crack in polymethylmethacrylate.

Fracture mechanics applied to engineering problems-strain energy density fracture criterion
G.C. Sih,B. Macdonald +1 more
TL;DR: In this paper, a design rationale for materials which contain flaws caused by metallurgical inclusions, fabrication and erection overloads, and fatigue cracking is outlined for materials that contain flaws.
