PhD Studentship in Mechanics of Materials at University College London

A PhD studentship is available in the Department of Mechanical Engineering at University College London, on the topic of "Detection and Identification of Damage in Composite Fibre/Metal Laminate Structures Using Guided Ultrasonic Waves". It is fully funded (fees + stipend) for UK citizens and EU citizens with UK residency (fees only for international students).

The academic group at UCL has an internationally leading profile and an exceptional publication record, and this project will provide numerous opportunities for high-profile publications and conference presentations. The project involves considerable interaction with other members of the research group, which has a very open, co-operative and friendly culture. The UCL laboratories are very well resourced with equipment, computers, consumables and all that is needed to perform research at the highest standard. The aim is to provide the best conditions for world-leading research.

Phase field fracture modelling using quasi-Newton methods and a new adaptive step scheme

Dear iMechanicians,

I hope this paper is of interest to you. We show that quasi-Newton methods make monolithic phase field fracture implementations very robust. Convergence and computations times orders of magnitude smaller than the usual staggered approaches are demonstrated in complex problems such as unstable cracking, fatigue or dynamic crack branching.

PhD Position in Multiscale Modeling of Materials

An immediate Ph.D. position is available in the Advanced Hierarchical Materials by Design Lab at Louisiana Tech University on multiscale modeling of materials synthesis. The candidates must have earned a degree in Mechanical Engineering, Chemical Engineering, or related fields (applicants with an MSc will be given priority) and have a solid background in theoretical and computational mechanics. Having knowledge of continuum mechanics, finite element modeling, and a programming language is a plus.

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.

When to use equation of state models in modeling high velocity impacts?

Equation of state models (Mie-Gruneisen equation of state etc) have been widely used to study hydrodynamic response of material during explosive deformation, ballistic impacts for a long time. As far as I understand, a hydrodynamic response is required to be incorporated in a model if the pressure of impact leads to an increase volumetric strength. That is the stress wave speed in the material exceeds the speed of sound in the material (v = sqrt(elastic modulus/density)).  Ballistic impacts occur at strain rates close to 10^9 to 10^12/s.
