I have found a pdf that has pretty extensive listings of mechanical properties for wood and I am trying to fill in all the orthotropic parameters for a Western Red Cedar at 12%mc as a new material in my FEA project. Here is a link to that pdf: https://www.conradfp.com/pdf/ch4-Mechanical-Properties-of-Wood.pdf
Here is the page in the pdf that begins its orthotropic discussion:
Here is my parameter table in the project which I need help with: https://www.simscale.com/workbench/?pid=4486940413736144120&mi=spec%3Ab9c08495-0fa1-4c19-bb4e-d9ed4ce9bacc%2Cservice%3ASIMULATION%2Cstrategy%3A54&ps=analysis%2Fmaterials%2F0
Here is my attempt at filling in the blanks with my notes and questions added on the image:
With those numbers my results don’t pass my internal reasonable meter 
Can an FEA expert please come to my rescue?
Maybe @BenLewis, my FEA hero of the past…
Thanks,
Dale
Hi @DaleKramer,
Thanks for this very pertinent question. I am from the FEA side, but I just worked with metallic materials throughout my career, so I am not the best guy to tell you how you can obtain these orthotropic values without an experiment (like a tensile test for wood I guess, not sure how it works for this material). But, let me tag @rszoeke here who likely have great insights on that.
As is usually happens, the clarity provided by forcing myself to present my issue into an organized forum topic allowed me to probably solve this issue myself.
After re-reading the orthotropic discussion in the pdf, which I linked to in this topics 1st post, I was able to calculate all the orthotropic parameter values that SimScale wants.
My only assumption now is that Grt = Gtr , I hope that is a close approximation and which I hope someone out there can ‘talk to’ by a further response to this topic.
Here is my self-corrected parameter table:

And some results that pass my internal reasonable meter at first glance:

Sorry for jumping the gun here.
