The question was raised in class as to what the appropriate equilibrium condition for a column of fluid at rest should be. Specifically, given we expect a hydrostatic gradient in pressure with height, whether  the chemical potential must be the same throughout the column was questioned. Here are my first thoughts. In brief, I assert that  the chemical potential must be everywhere identical, and that the pv term is balanced, at every height in the column, by the potential energy conferred by position in a gravitational field.

Dear colleagues,

I would like to bring to your attention the advanced course on Modeling of localized inelastic deformation that will be taught by Milan Jirasek in Prague, Czech Republic on 14-18 September 2009. 

More detailed information on the course is posted at http://mech.fsv.cvut.cz/~milan/course2009.html. We are looking forward to seeing you in Prague!

Dear All,

You are encouraged to submit abstracts for SAE 2010. The deadline for

abstract is June 1.

PROGRAM M106:

I have a 3D model in Abaqus of a wind turbine rotor, modelled with shell elements (S4R and S3). To use the same blade in an aeroelastic wind turbine code (HAWC2 from Risoe), I want to convert selected cross sections of the 3D model to Timoshenko beam elements.

In a previous post some months ago (see here), I mentioned some of the questions I had considering the aeroelastic response of a wind turbine rotor. In this post I just want to give, for those interested, a brief status report.
