Fatigue crack growth simulations of plastically graded materials using XFEM and J-integral decomposition approach

Engineering Fracture Mechanics, 2019
In this work, fatigue crack growth in functionally graded materials (FGM)/plastically graded materials (PGM) is simulated using the J-integral decomposition approach and extended finite element method (XFEM). The fatigue crack growth rate is estimated by

Numerical assessment of cyclic J-integral △J for predicting fatigue crack growth rate

Engineering Fracture Mechanics, 2019
The cyclic J-integral is a significant mechanical parameter to describe the elastic-plastic fatigue crack growth rate. A equivalent domain integral method based on finite element method was proposed for evaluating the cyclic J-integral.

The role of stress softening in crack propagation of filler reinforced elastomers as evaluated by the J-Integral

Engineering Fracture Mechanics, 2019
A recently developed micromechanical model of stress softening and hysteresis of filled rubber is used to calculate the energy density- and stress distribution around the crack tip for a given displacement field, which is determined by digital image ...

Coupled mechano-diffusion J-integral in active particles under the influence of binder

, 2020
The fracture of active particles in an electrode is an important source of the capacity fade in Li-ion batteries. A model for simulating the effects of cracks and binders on the Li-ion distribution, diffusion-induced stress (DIS), and J-integral of ...

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.

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 ...

On J-integrals in the plane fracture

Applied Mathematics and Mechanics, 1990
In this-paper, we discuss J-integrals near models I and II crack tips for the plates of linear-elastic isotropic homogeneous material and orthotropic composite material, using the theories of complex function and calculus, and obtain the result as follows:
