Large scale ab-initio simulations of dislocations
Dear fellow mechanicians,
I wanted to share our recent paper in Large scale ab-initio simulations of dislocations. A link with free access is provided.

Computer Graphics Algorithms and Image-Based Multiscale Multigrid Framework
We present a novel image-based multiscale multigrid solver that can efficiently address the computational complexity associated with highly heterogeneous systems. This solver is developed based on an image-based, multiresolution model that enables reliable data flow between corresponding computational grids and provides large data compression. A set of inter-grid operators is constructed based on the microstructural data which remedies the issue of missing coarse grid information.

On the suitability of slow strain rate tensile testing for assessing hydrogen embrittlement susceptibility
I hope that some of you will find this work interesting. We show that early cracking occurs in slow strain rate tensile testing (SSRT), which compromises the capabilities of this popular experiment for measuring hydrogen embrittlement susceptibility.

Wallner lines, crack velocity and mechanisms of fracture in a brittle bulk metallic glass
A few years ago, we observed Wallner Lines on the fracture surface of a brittle Bulk Metallic Glass and explained the process of formation of nanocorrugations on the fracture surface.
We published our research in Acta Materialia in the paper: 'Wallner lines, crack velocity and mechanisms of fracture in a brittle bulk metallic glass'.
I hope the experimental fracture mechanicians would particularly enjoy reading this paper and find it useful in their research.
On the mechanism and the length scales involved in the ductile fracture of a bulk metallic glass
A few years ago we published a paper in Acta Materialia elucidating the mechanism and length scales in the ductile fracture of bulk metallic glass through experiments and finite element simulations.
The link to the paper is here: 'On the mechanism and the length scales involved in the ductile fracture of a bulk metallic glass'.
I hope you enjoy reading the paper and find it useful in your research.
Fracture of notched ductile bulk metallic glass bars subjected to tension-torsion: experiments and simulations
There is a shortage of literature on mode III fracture behaviour of bulk metallic glasses.
In our following research paper published in Acta Materialia, we report our experiments and three-dimensional elasto-plastic finite element simulations of tension-torsion loading on notched ductile bulk metallic glass bars.
It is found that fracture toughness of this BMG is lowest in mode II among all three fracture modes.
