The Meaning of the Concept of Potential in Mechanics (and in Physics)

Submitted by Ajit R. Jadhav on

If someone knows of books/articles dealing with the meaning of the concept of potential in physics (or concerning the physical bases underlying the energy methods of mechanics) then I would very much appreciate getting to know about these.

Wondering about the Mechanics of Bacterial Death

Submitted by Ajit R. Jadhav on

0. I was idly thinking about the current H1N1 flue pandemic, and the following things occurred to me. Please note, I know very little about this subject matter. So, please consider descriptions in the following as, at best, tentative.



1. There is a basic difference between how alcohol kills viruses and how salt-water kills bacteria. [Alcohol is used in the hand-cleaners they use in hospitals. Girgling with salt-water is the first line of defense (and an unexpectedly highly effective one) which is well known for millenia.]



Fourth International Conference on Engineering Failure Analysis (ICEFA IV) - abstract deadline 27 November 2009

Submitted by Dan Lovegrove on

Following successful meetings in Lisbon, Toronto and Sitges, Elsevier will host the Fourth International Conference on Engineering Failure Analysis (www.icefa.elsevier.com) at Churchill College in Cambridge from the 4th - 7th July 2010. You are invited to participate in the latest in this important series of conferences, which have established a respected biennial forum for the discussion and dissemination of knowledge and experience in Engineering Failure Analysis.

8th International Conference on Fatigue Damage of Structural Materials - abstract deadline 7 December 2009

Submitted by Dan Lovegrove on

The eighth biennial Fatigue Damage of Structural Materials conference (www.fatiguedamage.elsevier.com) will once again be held in scenic Cape Cod at The Resort and Conference Center at Hyannis, Hyannis, Massachusetts from the 19 - 24 September 2010. Hyannis is situated on the historic Cape Cod peninsula just 90 minutes from either Logan International Airport (Boston, MA) or TF Green Airport (Providence, RI). 

Question in sequentially coupled thermal stress analysis using ABAQUS

Submitted by ganesh.anandakumar on

I was wondering if anyone has solved a “sequentially coupled thermal stress analysis” problem using ABAQUS?

If so, here is what I am looking to solve.

Let’s assume we solved for the temperature (T) as a function of time and space using the transient heat transfer analysis given certain BCs.

Clarifications o Stroh formalism

Submitted by Ramesh Babu.Manda on

sir,

I am solving some problomes for Stresses around holes for Anisotropic cases. In this connection most of authors have solved the stresses in cartesian co-ordinates only. Can I have any papers which are solved in polar co-ordinates by Stroh formalism for Stresses around holes in Composite laminates.So kindly help me

thanking you

von Karman plate equations

Submitted by Rui Huang on

Many of us (including myself) have used the nonlinear equations for elastic plates, originally proposed by von Karman (1910). I recently came across a book with some interesting comments about the plate equations, which may be of interest to share with others on imechanica. The book's title is "Plates and Junctions in Elastic Multi-Structures", authored by Philippe G. Ciarlet and published by Springer-Verlag in 1990.

looking for heat engine simulation software

Hi!



I am wondering if anyone here knows of a generic heat engine simulator. I.e. something that can simulate the behavior of reciprocating engines, Stirling engines, and so forth.



The outputs I'm interested in include things like power and efficiency. The input variables that I would play around with include engine dimensions and material properties.
