J-integral for Mode-III

2003
Write the general expression for the J-integral for anti-plane shear, i.e. mode III. Using the dominant elastic singularity, shrink the J-contour down to the crack tip and prove, by direct calculation ...

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.

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.

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.

Effects of Thickness on J-Integral in Structures

1983
The distribution of the Ĵ-integral, an extension of the J-integral, is calculated along the crack front of compact specimens of varying thicknesses by a three-dimensional elastic-plastic finite-element method. The Ĵ-integral takes the maximum value at the midthickness and smaller values near the plate surfaces, and the Ĵ-value at the midthickness ...

J-Integral and crack opening displacement fracture criteria

1990
The mathematical formulation of conservation laws applicable in elastostatics in the form of path independent integrals of some functionals of the elastic field over the bounding surface of a closed region originates from the work of Gunther [5.1]. Some years earlier Eshelby [5.2] obtained a representation of the ‘force on an elastic singularity or ...

On the J-Integral as Computed by Finite Elements

1988
Convergence tests on the computed J-integrals for a number of crack geometries were made using 8-noded plane stress isoparametric elements. The tests show that accurate estimates for J and the stress intensity factor k can be obtained by dividing the plate into regular meshes which can be generated automatically.
