New IOSO optimization software application examples in turbomachinery

Submitted by IOSOnier on

Dear Colleagues.

Let us introduce you some new application examples of IOSO optimization technology employment in turbomachinery.

 

 

First example is the application of IOSO software connected with Concepts NREC software aimed at improving efficiency of 10-stages compressor, you can download it from here

Post Doctoral Research Associate in the area of high strain rate loading and multiscale modeling at RPI

Submitted by Suvranu De on

There is an immediate opening for a postdoctoral research position in the Advanced Computational Research Laboratory at RPI, Troy NY to work on problems involving high strain rate loading conditions and multiscale modeling. Encouraged to apply are creative, self-motivated candidates with a sound background in computational mechanics. RPI is home to the CCNI, one of the most powerful university-based super-computational research facilities in the world.



Qualifications:

1.    PhD in Computational/Applied Mechanics or related topic.

Wendtland (1972) experimental results on natural frequencies of cracked cantilever beams

Submitted by aysha.kalanad on

The effects of edge cracks on the natural frequencies of cracked cantilever beams have been extensively studied by Wendtland (1972). These results are referred to by quite a number of related journal papers; the refernce is:

Wendtland D. A¨ nderung der biegeegenfrequenzen einer idealisierten Schaufel durch Risse. Ph.D. Dissertation, University of Karlsruhe; 1972.

Does anyone know how this can be accessed online, or atleast the complete set of results for eigenfrequency (first three modes of vibration) changes due to edge cracks at different positions and depths?

Post Doc position available in hybrid design of armor panels (with ceramics, composites) @ NTU, singapore

Submitted by karthic_newbee on

There is a Post doctoral Position available with my supervisor Prof.Sridhar Idapalapati.  The candidate should have PhD degree with background in  impact mechanics, fracture mechanics and exposure to finite element modeling packages such as AUTODYN software. Exposure (handson) to drop tests or Hopkinson bar tests is an added advantage.

If u are interested plz contact him directly @ msridhar [at] ntu.edu.sg

 

Experimental Observations of Stress-Driven Grain Boundary Migration

Submitted by Tim Rupert on

My coworkers (Dan Gianola, Yixiang Gan, and Kevin Hemker) and I have published research results in the December 18th, 2009 issue of Science.  In this work, we perform tension tests on specially designed thin film samples to studying the influence of different stress and strain states on mechanically-induced grain growth in nanocrystalline aluminum.  Our results indicate that shear stresses drive grain boundaries to move in a manner consistent with recent molecular dynamics simulations and theoretical predictions of coupled grain boundary migration.
