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.
