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 ...

Invariance of the J-integral in plastic deformation

Strength of Materials, 1986
1. A method was worked out for the highly accurate measurement of arrays of displacements by the method of speckle photography. The displacement fields were determined innotched specimens loaded by three-point bending. The error of measurement does not exceed 1.5%. 2.

Analytical Applications of the J-Integral

1973
It has recently been shown by experiment that a quantity known as the J-Integral may be a useful fracture criterion in the inelastic range. The mathematical definition of the J-lntegral is first used here, in combination with some simplifying assumptions, to derive the known relationship between the conventional elastic stress concentration factor of a

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.

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.

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.

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.
