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?

As far as I can see, the possible choices are:

-- Griffith (G)
-- Irwin (I)
-- Some other person (Please specify)
-- None. The physical quantity KIC is not necessarily the best measure of toughness... We should wait for the research to evolve a better measure.
-- Something else (though I fail to see what it could be)

Please note, this is not a suggestion for a poll. (I mean, rather, that things like this should never be finalized purely by polls alone!) 

But anyways, I would appreciate knowing what you think... Please leave your comment below...
