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.

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.

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.

Bulk Metallic Glasses were found to exhibit an intermediate temperature minimum in ductility. Does it also lead to an intermediate temperature minimum in fracture toughness?

Porous Bulk Metallic Glasses have been found to be mechanically superior under compressive stress states.

Porous Bulk Metallic Glasses have been invented by researchers to mitigate catastrophic failure in monolithic Bulk Metallic Glasses which are susceptible to intense strain localization into shear bands.

PhD positions are available in Dr. Caizhi Zhou's group in the Department of Mechanical Engineering - University of South Carolina. Research projects may involve crystal plasticity finite element modeling. The students will receive rigorous training and interact intensively with their academic advisor. The financial support will be in the form of GRA with a monthly stipend of approximately $2500 for 12 months each year (the tuition will be waived). Financial aids are also available for students to attend professional conferences. 

Hello dear all

I have a question about the weak formulation.

It's my pleasure if one dear person guides me.

please see the small attached PDF file.

We are seeking motivated PhD students with a background in mechanical engineering, material science, physics, chemistry, or in a closely related field. Candidates with interests in (but not limited to) one or more of the following areas are particularly encouraged to apply:

· Material properties under high strain rate deformation;

· Energy absorption and protection against impact, vibration and blast;

· Nanoporous materials, including MOFs, zeolites, and silica;

· Nanofluidics and microfluidics;
