Welding Research Council Contact Details

[EJ_]

Hello everybody! Long time reader, first time poster.

Does anyone know what's happened to the Welding Research Council, specifically how to contact them?
I believe their official website is forengineers.org, but it just shows a generic landing page.
My attempts to email mprager@ or bulletinsales@forengineers.org bounces back as undeliverable. (Taken from google searches which indicate to email either of these emails to enquire about buying WRC docs.)

(I was trying to contact them regarding MPC Project Omega related items.)

Thanks,
EJ

You may want to contact Paulin Research Group and review their products

Many are based on WRC methodologies and offer a reasonably priced alternative

Thanks, we already have NozzlePro for nozzle analysis.

I'm specifically looking at high temp creep, and I understand WRC/MPC (Materials Property Council, which I understand is a part of the WRC) developed the MPC Project Omega method, and I assume they assisted the API committee with the practical implementation of the method in API579 section 10. I'm implementing the method as a subroutine in Abaqus, and have found some computational stability issues for low stress states with high triaxiality.
I've reviewed WRC bulletin 554 which has some useful info about stress ranges etc, but doesn't quite match up with the API579 implementation.
I'm finding Omega explodes at low stress for some materials (800HT), which coupled with the multiaxial exponent, can lead to incorrect damage rates. (i.e. can get strainrate 1e-30, with damage rate 1e30 which is nuts, and doesn't correlate with the behaviour for other materials.)

Thanks,
EJ

I believe WRC is now controlled by E2G, not sure if the

http://www.forengineers.org

site is to be discontinued or not.

Thanks BJI, that name popped up in some of my past searches, and the authors of WRC554 all seem to be there, so I've emailed E2G.

Explicit integration is only conditionally stable; does adjusting your minimum time step help?

How are you doing your differentiation in the subroutine? Accurate differentiation can be important for convergence.
