Cyclic J-integral: Numerical and analytical investigations for surface cracks in weldments

Engineering Fracture Mechanics, 2017
The cyclic J -integral (Δ J -integral) is a crack tip parameter of elastic-plastic fracture mechanics which can be used as governing parameter for the description of fatigue crack growth (FCG) in metallic structures.

Time dependence of J-integral

Nuclear Engineering and Design, 1983
Abstract Tests performed within the framework of earlier RWTUV projects together with results obtained elsewhere with regard to the time dependence of fracture mechanics data show that time effects reduced the toughness of materials, according to the nature of the test (extremely slow load rate or hold times with sustained load).

J-Integral Estimation Procedures

Journal of Pressure Vessel Technology, 1983
This paper presents efficient procedures for estimating the J-integral, a parameter for characterizing stable crack growth under inelastic conditions. Two different formulations are shown. The basis of the first approximate J-integral formula is the familiar extension of the elastic strain energy release rate computation for elastic-plastic loads. This

Evaluation of mode-I SIF, T-stress and J-integral using displacement data from digital image correlation – Revisited

Theoretical and applied fracture mechanics (Print), 2018
Digital image correlation (DIC) is a unique technique for determining displacements because in a single experiment one can get ux and uy displacements if it is 2D DIC and all the three components if one uses 3D DIC.

J integral for delaminated composite laminates

Composites Science and Technology, 1993
Abstract An integral, J, is derived for edge-delaminated composite laminates subjected to pure bending and/or uniform axial extension. This J integral for a quasi-three-dimensional edge-delamination problem subjected to uniform extension has the same form as Rice's J integral for a two-dimensional crack problem.

SOME PROBLEMS IN THE J–INTEGRAL

Engineering Fracture Mechanics, 1984
Abstract For a blunt crack the j -integral is path dependent on contours which are very close to the crack tip even for elastic material. Using the incremental J -integral theory we introduce a new parameter J t , characterizing the behavior of a crack tip and prove that the J -integral is almost path independent on contours whose radii are ...
