  John Deere, courtesy of Mohamad El-Zien and Jin Qian, have set up 
a challenge to those of our committee who think they can predict
the life of real life welded components.  Details of the challenge
are available at www.fatigue.org web site:

    http://www.fatigue.org/Weld/weld.html

in a downloadable *.doc  file.

Hint 1:
Jin Qian forwarded an additional hint:
   "The info I got on this was:  A13, Yield stress about 50 ksi."

Hint 2:
 The AISC Manual of Steel Construction should give the section
properties.  

The fatigue analysis is up to you.

The challenge is:

     So, how good are you at fatigue life prediction?

(The above description is a liberal interpretation of the
problem as given to me for distribution and any 
unclarities are probably my fault alone.)

ps.: Results to be compared at the up-coming meeting; details follow.

  A number of the committee members have mentioned that
they are in the process of preparing a solution for the weld
challenge issued courtesy of Mohamad El-Zien from John Deere.
Several of you have requested some time to present results.

  If you have a solution and wish to present it to the committee
at the up-coming meeting in Peoria, (April 15,16) please let
John Hakala or myself know that you would like some presentation
time.  Depending on the number of requests we may go to a variation
of "Woehler Symposium Rules":  (1 visual aid) + (5 or 10 min. talk)

  Please let us know if you may need some time to present.
John Hakala:  Jmhakala

Thanks,
