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.

Determination of J-integral of asphalt concrete based on SC(B) test configuration and image analysis

, 2020
The J-integral of asphalt concrete is usually measured with multiple specimens used for fracture tests because crack growth is not usually monitored during the fracture test. This research uses an industry digital image camera to monitor the crack growth

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.

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 ...
