International Journal of Fatigue, 2019 The elastic-plastic J-integral is adopted to correlate fatigue crack growth data of ductile metals. An analytical link is known to exist between the J-integral and the strain energy density averaged in a control volume embracing the crack tip.

Applying fracture mechanics to cracked components subjected to unloading [PDF]
, 2016 The J-integral is widely used as a fracture parameter for elastic-plastic materials. The J-integral describes the intensity of the stress field close to the crack tip in a power-law hardening material under a set of well-known restrictions.

Stress intensity factors computation for bending plates with extended finite element method [PDF]
, 2012 The modelization of bending plates with through-the-thickness cracks is investigated. We consider the Kirchhoff–Love plate model, which is valid for very thin plates.

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.
