As the 2010 SIMULIA Customer Conference approaches, it reminds me of a thought-provoking presentation given by Dale Berry of SIMULIA at the 2009 SCC in London.

He reminded the audience, of engineers and researchers, that Realistic Simulation is not only good for evaluating mechanical behavior of product performance, but it’s also an indespenible tool for driving innovative research that improves our lives and society.

Hi All, thanks in advance for any replies.

I am currently doing my Thesis on fast stress analysis using the boundary element method and specifically, adaptive cross approximation. I ofter come across the terms "single layer potential" and "double layer potential", i "know" what they are mathematically, i was wondering if anyone could give me an insight into what they mean physically, or just give a simple non mathematical definition? Thanks a lot, Ian.

hi

i am having problems solving two solid mechanics problems... can anyone please help??? the problems are:

Question 4:

A 2380 Nm torque is applied to gear D due to input torque from the motor at A, as shown in figure 4. Shafts 1 and 2 are both solid steel, 44 mm in diameter and 600 mm long. Gear B has a diameter of 250 mm and gear C has a diameter of 350 mm. The shear modulus G for steel is 80GN/m^2

The best place to start is Wikipedia: http://en.wikipedia.org/wiki/Stereology.

Most active research in stereology is done in medical and biological community.

In engineering, in USA, Prof. Rhines and Prof. de Hoff, both of the University of Florida at Gainesville did a lot of pioneering work. The stereological researchers active in engineering in USA are mostly limited to the "progenies" of the Florida school. These include (and I quote off-hand): Prof. Arun Gokhale of GeogiaTech and Prof. Burton Patterson of the University of Alabama at Birmingham (who was my guide at my first attempt at PhD). 

This model has a simple closed-form analytical expression, matching with finite element results nearly perfectly.

dear Imechanica users,

a wonderful location for our annual italian conference in stress analysis -- see www.aias2007.it. It is organized by our collegues in Università di Napoli, Prof. Renato Esposito. Attached the call for papers in PDF, and more info are below.
