Gerald,
you know that I am very interested in any information with regard to weld-simulation.
Since here one combines - or tries to - both arc- and solid state physics to achieve what is normally hard or nearly impossible(?) to achieve.
Predictions on what might happen while the welding-process is running or how the welding process affects the welded base material.
It is in my personal opinion an incomparable and tremendous field of investigation, information and a great opportunity for very own personal endeavor. Much too much for a single human being in a single human life, I honestly know that, but nonetheless I love it..!
This what you have mentioned is a fraction of a very interesting presentation coming from Professor Tarasankar DeBroy from the Pennsylvania State University, which is - as far as I am correct - one of the world wide leading institutes in the field of computational welding simulation.
He has held this presentation named:
«Tailoring Fusion and Friction Stir Welds using a Reliable and Efficient Transport Phenomena based Model and a Genetic Algorithm»
on the
8th International Seminar
Numerical Analysis of Weldability
been held in Graz in Austria in 2006, see also:
http://iws.tugraz.at/IWS_tree/Veranstalt/Seggau/2006/e_seggau_programme.htmlWithin the presentation he treats the Friction Stir Welding and the Gas Tungsten Arc Welding process as examples for an introduction of what Numerical Analysis is meanwhile able to achieve in the field of Simulation.
Although I unfortunately couldn't attend personally, I had the luck to receive the presentations, however, because my colleagues from our "Numerical-Simulation-Department" were there. You know, where my friend the PhD in Mathematics is the head of (he who has the patience to "explain" me math from time to time :-)).
Gerald, unfortunately there are Copyright reasons making it impossible to share the details of DEBROY's presentation with the forum, although I incredibly would like to!
Nonetheless, what I would like to do is to attach the specific slide which you have mentioned in your kind reply hereinafter for your kind information. I guess by that I won't contravene any governing laws of Copyright.
Furthermore I guess as well, it is not prohibited to write me a short private message, for a continued discussion of this interesting presentation. You know what I mean?
So I ask your kind understanding for what I have described and remain with as always
best regards,
Stephan
