In the attachment, we show that Truesdell rate can by simplified to Green-Naghdi rate by assuming F .=. R and can be further simplified to Jaumann rate by assuming W .=. R(.)R(T), where .=. means approximately equal

In a stretch dominant deformation, the three rates give different stress rate. This is usually explained by that we need a different tangential modulus for different objective rate. However, it is hard to understand why we need to change "material" modulus when we use a different "mathematical" form of objective rate as they are all supposed to be equivalent.

The FY 2009 Nanotechnology Undergraduate Education (NUE) in Engineering Program Solicitation has just been released (NSF 09-533).  http://www.nsf.gov/funding/pgm_summ.jsp?pims_id=13656&org=EEC&from=home

The University of Chile invites applications for two full time faculty positions in Mechanical Engineering. Applicants must have deep interest in undergraduate and postgraduate teaching, as well as the purpose to conduct long term, externally funded research programs at international level. Candidates are also expected to maintain fruitful work relationships with industry in their respective areas. According to qualifications, they may be ranked at the Assistant or Associate Professor level. Candidates are sought in two areas:

1. Energy: Research interests in conventional or alternative energies, with emphasis in energy conservation, generation or efficient use.
