Experimental measurement of the J-integral

Engineering Fracture Mechanics, 1984
Abstract A direct measurement of the J-integral in plane stress state is carried out by utilizing the definition of J as a line integral; the integration function is assessed along a suitable path in rectangular-shaped cracked panels by means of strain gauges.

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 ...

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

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.

Computation of the J‐integral for large strains

Communications in Numerical Methods in Engineering, 2007
AbstractThe phenomenon of failure by catastrophic crack propagation in structural materials poses problems of design and analysis in many fields of engineering. Cracks are present to some degree in all structures. They may exist as basic defects in the constituent materials or they may be induced in construction or during service life.Using the finite ...
