Our group has recently published an article wherein we propose the use of X-ray computed tomography coupled with statistical nanoindentation for simulating the mechanical properties of quasi-brittle materials. The approach is used for simulating tensile properties of hardened cement paste.

PhD openings in Computational Solid Mechacnis @ MEGroup

The National Center for Additive Manufacturing Excellence (NCAME) at Auburn University is announcing for two fully-funded PhD positions in the area of structural integrity of additive manufactured (AM) materials/parts. These students will work under direction of Dr. Shamsaei from Mechanical Engineering Department. These opportunities include;
1- One PhD student is expected to work on experimental and analytical mechanics, additive manufacturing, fatigue testing and modeling, failure analysis, microstructural characterization, and fracture mechanics.
2- The second PhD student will implement computational mechanics to investigate structural integrity of AM parts. The candidate for this position should have background on crystal plasticity and finite element analysis. This candidate is also expected to be familiar with a finite element software including writing subroutines.
For international applicants, you need to have your TOEFL and GRE scores ready to report by Oct. 15th. If interested, please send your resume and a cover letter, briefly explaining your relevant experience and publications to Dr Vaziri (mzv0045 [at] auburn.edu).

Virtual forming of electronic components made of copper alloys

I noted with interest the recent iMechanica blog entry regarding the fact that only a small minority of experimentalists are willing to share raw data. I was somewhat surprised. I instinctively felt that theoreticians and comptutational scientists would have a different attitude.

Experimental data availability is a cornerstone for reproducibility in experimental fracture mechanics. This is how the technical note begins, the recently published 

"Long term availability of raw experimental data in experimental fracture mechanics", by Patrick Diehl, Ilyass Tabiai, Felix W. Baumann, Daniel Therriault and Martin Levesque, in Engineering Fracture Mechanics, 197 (2018) 21–26.
