Naming the SI Unit for Fracture Toughness (KIC)

Submitted by Ajit R. Jadhav on

To: Engineers, Fracture Analysts, Mechanicians, Physicists...

In science and engineering, we have an excellent tradition: naming a physical unit using the name of a prominent personality from the concerned field. For example, in SI system, we measure force in newton, work in joule, power in watt...

But the unit of fracture toughness, i.e. KIC, is too lengthy to pronounce: (mega) pascal-underoot-meter. Further, it has also been in use for something like half a century by now, perhaps more. So, how do you like the idea of giving a name to this unit?

Achenbach Receives National Medal of Science

Submitted by Carl T. Herakovich on

Jan D. Achenbach, Walter P. Murphy Professor and McCormick School Distinguished Professor at Northwestern University was presented a 2005 National Medal of Science by President George W. Bush on July 27. Achenbach, who  is well known in the mechanics community, was honored for his seminal contributions to engineering research and education in the area of wave propagation in solids and for pioneering the field of quantitative non-destructive evaluation. Previously, Achenbach received a 2003 National medal of Technology from President Bush.

How could we use the energy of the high speed air, which is coming out from a pipe to the atmosphere?

Without increasing the pressure in the outlet of the pipe?

I mean we want to transfer air from point A to point B using a piping system which is equipped with a fan. Now there is energy lost in the outlet because the air exits with velocity in the atmospheric pressure, so the problem is how to use this energy ( high speed air) without increasing the pressure in the outlet of the fan. offcourse if it was water instead of the air, we could get the energy by installing a turbine next to the outlet pipe and still let the water come out in the atmospheric pressure

Submitted by Rui Huang on

As a member society of the U.S. National Committee on Theoretical and Applied Mechanics (USNC/TAM) , the objective of the American Academy of Mechanics (AAM) is the advancement of the science and profession of mechanics.

The scope of AAM includes all of the disciplines involved in the modeling and study of the response of inanimate and animate matter to forces and environmental effects.
