On the cyclic J-integral of a 3D semi elliptical surface crack [PDF]
, 2014 This paper investigates an approach for calculating the cyclic J-Integral (ΔJ) through a new industrial application. A previously proposed method is investigated further with the extension of this technique through a new application of a practical 3D ...

J-Integral Evaluation of Small Specimens.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1992 Three-dimensional elastic-plastic analyses were carried out for two small specimens using finite deformation theory. For a 1/4-inch compact tension specimen of 1 mm thickness, the J-integral along the crack front is higher at the midsection of the specimen than at the surface of the specimen.
