The J-integral in flexoelectric solids

International Journal of Fracture, 2018
The flexoelectric effect is a significant electromechanical coupling phenomenon between strain gradients and electric polarization. Since the design of materials with high flexoelectricity should be accompanied with stress concentration/intensity, the strength and fracture analysis of flexoelectric materials with large strain gradients is desired.

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:

Modelling hydraulic fracturing with the J-integral

2021
<p>Hydraulic fracturing plays a central role in engineering fractured reservoirs. To simulate the propagation of “dry” fractures, the J-integral has been a standard technique. Its superior accuracy at coarser resolutions make it particularly attractive, especially for reservoir-scale simulations.

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.

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

Analytical Applications of the J-Integral

1973
It has recently been shown by experiment that a quantity known as the J-Integral may be a useful fracture criterion in the inelastic range. The mathematical definition of the J-lntegral is first used here, in combination with some simplifying assumptions, to derive the known relationship between the conventional elastic stress concentration factor of a

Experimental measurement of the J-integral

Engineering Fracture Mechanics, 1984
Abstract A direct measurement of the J-integral in plane stress state is carried out by utilizing the definition of J as a line integral; the integration function is assessed along a suitable path in rectangular-shaped cracked panels by means of strain gauges.

On the J-integral in periodically layered composites

International Journal of Fracture, 1996
When a heterogeneous elastic material is represented by an effective homogeneous elastic solid, average stress and strain fields are used. The meaning of the J-integral in the effective homogeneous solid is investigated. A periodically layered medium is considered.
