Open Postdoc on computational methods and inverse problems

Submitted by Andrew J. Gross on Fri, 01/10/2025 - 18:03

uncertainty quantification

A Postdoctoral Fellow is sought to fill an immediate opening in the Gross Materials Lab at the University of South Carolina to work on a DARPA funded project. The postdoc will have the opportunity to attend regular meetings with DARPA and other DOD program managers. The research is focused on extracting yield surfaces from data rich full-field experimental information by solving an inverse problem.

job

We are hiring a postdoc to work on the mechanics of solid state batteries. The postdoc will be based at the Mechanics of Materials Lab (Department of Engineering Science, University of Oxford) and work co-supervised by Profs Laurence Brassart and Emilio Martinez-Paneda. A close collaboration with experimentalists in the Pasta Group (Materials Department) is also expected.

Leonardo's universal friction coefficient is found to be universal after all!

tribology granular materials

It turns out that friction coefficient 0.25 suggested as universal by Leonardo da Vinci more than 500 years ago has some universaility, as minimum friction coefficient for any granular material: it makes me proud as italian ;)

I guess it would be interesting to show this experimental result also theoretically or numerically, any interest?
