Hi Everyone,

 I would like to measure the residual stress imposed pattern through thickness of the plate by forming process (bending). Is it possible?

 I came to know that residual stress measurement through HOLE DRILLING METHOD offers only on the surface. That too, applicable only when residual stress imposed is uniform through thickness (like shot blasting process). If any one came across the experience of residual stress measurement, please throw some light in this regard.

 Thanks in advance

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.

Hello All//

I am always confuing on that Stress is a point Function..and not Seen Physically Than Stress is a material Property or Material Behaviour?

Waiting For Answer..

Thanks..

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?

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

Hello Everyone,

Could you address me to a comprehensive description for relationship between fatigue and fracture  in prediction life Fatigue crack growth life?

i appreciate in advance,
