The Applied Mechanics Division, of the American Society of Mechanical Engineers, seeks nominations for the awards listed below. All the awards are international. Neither the nominee nor the nominator need be a member of the ASME. However nominators must not be active members of the respective award committees. Further descriptions of the awards are given at http://divisions.asme.org/amd/Honors_Awards.cfm. A PDF version of this announcement can be found as an attachment at the end of this blog entry.
Understanding the dynamic stability of bodies in frictional contact steadily sliding one over the other is of basic interest in various disciplines such as physics, solid mechanics, materials science and geophysics. Here we report on a two-dimensional linear stability analysis of a deformable solid of a finite height H, steadily sliding on top of a rigid solid within a generic rate-and-state friction type constitutive framework, fully accounting for elastodynamic effects.
In the present paper, weakly enforced no-slip wall boundary conditions are revisited in the context of Large-Eddy Simulations (LES) with near-wall modeling. A new formulation is proposed in the framework of weakly enforced no-slip conditions that is better aligned with traditional near-wall modeling approaches than its predecessors. The new formulation is tested on turbulent open-channel flows at friction-velocity-based Reynolds numbers Reτ=395Reτ=395 and 950 benchmark problems.

The Computational Mechanics group at The University of Iowa, led by Professor S. Rahman, is looking for new Ph.D. students, who are capable of and interested in performing high-quality research on engineering design. The research, supported by National Science Foundation and others, entails building a solid mathematical foundation, devising efficient numerical algorithms, and developing practical computational tools for stochastic design optimization. A substantial background in solid mechanics and structural optimization is a must; exposures to stochastics and probabilistic methods are highly desirable.
If you are interested in pursuing a Ph.D. degree at Iowa, please contact and send a resume to: Professor Sharif Rahman at sharif-rahman [at] uiowa.edu. Please note that we are interested in students who already have M.S. degrees in engineering or mathematics. The desired start date is Spring 2016 or sooner.
