J-Integral Evaluation of Small Specimens.

open access: yesTRANSACTIONS 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.

Stress intensity factors computation for bending plates with extended finite element method [PDF]

open access: yes, 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.
