The research on stretchable and twistable electronics by Yonggang Huang at Northwestern University and John A. Rogers at the University of Illinois at Urbana- Champaign has been featured on the cover of the NSF Budget Request to the United States Congress for the fiscal year 2011.

ScienceWatch.com (affiliated with Thomson-Reuters), has ranked University of Illinois as the most cited institution in engineering from 1999 to 2009 (http://sciencewatch.com/inter/ins/10/10febTOP20ENG/).  It is followed by Berkeley, MIT, Stanford, University of Michigan, and Georgia Tech.
 

there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process?   if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions? 

I appreciate if you also put your comment in my idea?

Bes Regards,

Gyroscopic effects is a very old topic.

When reading
literature, I am confused by the two concepts: "gyroscopic moment", and
"Coriolis force". Are they exactly the same thing or different? what's
the difference between them if different?

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 reliability-based design optimization.  The research, supported
by NSF and others, entails developing new theory and efficient algorithms for stochastic
computing and design optimization. A solid background in mechanics and elementary
numerical analysis is a must; some exposure to uncertainty and probabilistic methods is
desirable.

frequency responce- how to track natural frequency of the beam using Abaqus? may i have the example of doing that? and the details that need to be considered.

Thanks.

Welcome to February 2010 Journal Club!  This month, I look forward to a lively discussion on the mechanics of structured and patterned interfaces in which geometry is used to tailor adhesion.  Much of the work in this area has been inspired by a variety of animals and insects that have feet covered with small structures (often hierarchical and sub-micrometer in size at the end) that allow them to strongly adhere to a broad range of surfaces.  The best known example is the Tokay Gecko (Gekko gecko), which can achieve an adhesion force much greater than its body weight and can quickl

We present an interesting application of ADINA FSI in cardiovascular mechanics, specifically, a potential cause for heart attacks is studied.  Please see
