Mathematical basis of virtual work

I am looking for a reference where I can find a mathematical proof of the principle of virtual displacements (work)

Physical Foundations of Continuum Mechanics

After many publications and lecture notes, Prof. Ian Murdoch has finally organized much of that material in the form of a book.

I am very hopeful that like Prof. Murdoch's lectures, this monograph will also help the readers to develop a better understanding of the physical aspects of mechanics. It will be a valuable addition to the researchers' personal collection.

Use Only the Angular Quantities in Analysis? Three Sample Problems to Consider...

A recent discussion at iMechanica following my last post here [^] leads to this post. The context of that discussion is assumed here.

I present here three sample problems, thought of almost at random, just to see how the suggestions made by Jaydeep in the above post work out.

Are Linear and Angular Momenta Interconvertible?

To the best of my knowledge, the two momentum conservation principles, namely, the conservation of linear- and angular-momentum, operate completely independent of each other. For an isolated object, there is no possibility of conversion of one form of momentum to the other.

Career after the Ph.D.

Hi,

I'm an Engineer and a Ph.D. student in Applied Maths, working in the field of Nonlinear Finite Elements for Elasticity. I often think about my future career since, by now, I have a strong experience with coding FE in C++/Matlab/Mathematica, but no clue whatsoever about commercial black-box softwares for FEA. I'm worried about this, since most of the job vacancies from the industry (I'm not interested in pursuing the Academic career) seem to require only experience with a specific software and application, and not to directly code FE.

I want to find a reference to learn about motion groups SE(N). Any recommendations will be appreciated. Regards, Deepak Trivedi

A lack of heroes, a lack of open culture

One of the things that I've thought about often in relation to mechanics is:

Why lionize mathematics in science/engineering?

This has reference to (only) the *last paragraph* in Prof. Harry Lewis' recent post, found at: node/1423#comment-2880.

The reason I write the present post is because I always seem to have had a view of inventing, learning, or teaching mathematics that is remarkably at odds with what Prof. Lewis' last paragraph *seems* to imply.
