Hello everybody,
I am working on FE Simulation of interface cracks. To this end, I use modified VCCT, CSDEM and other such methods to determine mesh independent strain energy release rate (G) and Mode mixity (ψ). Now I have a fundamental doubt.
In a cooperative research between PoliMi and UIUC we have analyzed the crack growth in Ni-based single crystals:

Crack growth experiments analyzed with DIC had shown relatively low closure levels respect to polycrystals. Crystal plasticity simulations with WARP3D have been able to simulate closure levels consistent with the experimental ones.
Abstract: In this paper, we provide a retrospective examination of the developments and applications of the extended finite element method (X-FEM) in computational fracture mechanics. Our main attention is placed on the modeling of cracks (strong discontinuities) for quasistatic crack growth simulations in isotropic linear elastic continua.

Stress corrosion cracks can be a serious problem in many engineering industries, and especially so for critical parts. While an ultrasonic transducer can be used for the non-destructive evaluation of cracks with simple shapes, complex branching cracks, such as stress corrosion cracks, require ultrasonic arrays that consist of multiple transducers and are able to inspect at multiple angles.
Hi all,

Even Jay Leno tried to understand fatigue cracks at his Yesterday’s Tonight Show, our research on fracture and failure mechanics is received great attention from the general public. Read more after this photo--
