A post-doctoral position in the area of modeling the strength and deformation of FCC metallic specimens at the nanoscale. The study, which will be executed at the Nanomechanics Simulations Laboratory at the Technion, is available in the framework of and Israeli program for outstanding post-doctoral researchers from China and India.

Dear all,

In recent years, it was suggested that the strength of nanoscale
structures increases with speciman size as a power-law. This has been demonstrated
many times for pillars, both experimentally and in discrete dislocation
dynamics simulations. Various values for the power-law exponent in pillars were
obtained, and most of them are about -0.6. However, I did not manage to find
any theory which explains both this typical behavior and the values of the exponent.
Is it a phenomenological law? If not, can anyone refer me a detailed model?

Thank you in advance,

Dan
