Graduate research position - Modeling of composites (US Citizens only)
A graduate position is opened in Advanced Hierarchical Materials by Design Lab at Louisiana Tech University on multiscale modeling of composites. The candidates must have earned a degree in Mechanical Engineering or related fields, and be a US Citizen. Candidates with a solid background in theoretical and computational mechanics, specifically continuum mechanics and finite element modeling are preferred. Familiarity with FEM software package COMSOL is a plus.

Symposium on Microstructure - Property Relationship in 3D Printed Metals
The highly non-equilibrium and complex (thermal, mechanical, fluidics) processes in additive manufacturing lead to different microstructure and defect mechanics that is a major barrier for adaptation of this attractive manufacturing technique.
A very simple estimate of adhesion of hard solids with rough surfaces based on a bearing area model
"A very simple estimate of adhesion of hard solids with rough surfaces based on a bearing area model" is in press in Meccanica, can be viewed at http://rdcu.be/s0lV Abstract In the present note, we suggest a single-line equation estimate for adhesion between elastic(hard) rough solids with Gaussian multiple scales of roughness.

A theoretical study on the piezoresistive response of carbon nanotubes embedded in polymer nanocomposites in an elastic region
Herein, we report a theoretical study of polymeric nanocomposites to provide physical insight into complex material systems in elastic regions. A self-consistent scheme is adopted to predict piezoresistive characteristics, and the effects of the interface and of tunneling on the effective piezoresistive and electrical properties of the nanocomposites are simulated. The overall piezoresistive sensitivity is predicted to be reduced when the lower interfacial resistivity of multi-walled carbon nanotubes (MWCNTs) and the higher effective stiffness of nanocomposites are considered.
Measuring the relative density of open cell metal foams
Hello,
I would like to know how to measure the density of open cell porous iron foam. I am studying the mechanical behavior of pure iron foams for which I need to compare the relative densities of different foam samples. Could the density of the foams be simply calculated by the mass over the bulk volume (volume of the struts + volume of the pores) of the foam? Can I use Archimedes principle to calculate the foam density given that I have open cells? What is the best method to calculate the foam density?
Best Regards,
Reza
