Rubber Fracture Characterization Using J‐Integral

Tire Science and Technology, 1988
Abstract The use of the J‐integral to investigate fracture characterization in a carbon black reinforced natural rubber is described. Three applications to crack initiation are included: two based on the use of a hypothetical zero specimen length and one on conventional testing procedures for metals.

Das J‐Integral — ein neues Bruchkriterium

Materialwissenschaft und Werkstofftechnik, 1976
AbstractDas vonRicein die Bruchmechanik eingeführte J‐Integral beschreibt den Zustand an der Rißspitze auch bei großer plastischer Zone und ist daher als Bruchkriterium geeignet. Die Arbeit gibt einen Überblick über die experimentellen Methoden zur Bestimmung von J‐Werten und insbesondere des kritischen Wertes beim Einsetzen der Rißverlängerung ...

J-integral under transient temperature state

Engineering Fracture Mechanics, 1992
Abstract For a cracked plate under a transient temperature distribution, the J -integral is expressed in the form of a line integral by using the convolution integral. The J I -integral is calculated for a center-cracked steel plate under thermal and mechanical loading conditions and the calculated values are in good agreement with previous ...

The Time-Averaged Elastodynamic J-Integral

International Journal of Fracture, 2000
The time-averaged path independent J-integral for a stationary crack subjected to time-harmonic elastic waves is introduced. It can be determined from remote fields providing an alternative approach to compute the stress intensity factors. The J-integral is evaluated for a semi-infinite crack impinged by a plane sheer wave at an oblique angle.

Modelling hydraulic fracturing with the J-integral

2021
<p>Hydraulic fracturing plays a central role in engineering fractured reservoirs. To simulate the propagation of “dry” fractures, the J-integral has been a standard technique. Its superior accuracy at coarser resolutions make it particularly attractive, especially for reservoir-scale simulations.

On Three Dimensional Generalized J-Integral

1986
According to slice model, three dimensional J-Integrals are derived with consideration of effects about curvature of crack front and temperature fields. These integrals are proved to be path-independent and convergent. The relationship between the J-Integrals and stress intensity factors are established.

Estimation of J-Integral Uncertainty

1980
A method for determining the effect of random experimental error on the calculation of J and crack length extension Δa is presented. Predictor-corrector equations for determining Δa are also derived and their convergence properties studied. The application to a three-point bend specimen is considered and numerical results presented.

Einige Erhaltungss�tze der Kontinuumsmechanik vom J-Integral-Typ

Ingenieur-Archiv, 1981
Aus der Translations- und Rotationsinvarianz der allgemeinen Bilanzgleichung der Kontinuums-mechanik werden Erhaltungssatze in Form von Oberflachenintegralen hergeleitet. Fur die Energiebilanz folgen daraus Erhaltungsgrosen vom J-Integral-Typ, die sich in den Fallen der Statik, der stationaren ebenen Welle und der Hyperelastizitat besonders ...
