Hadn't seen this thread before but last time I had seen the only bokken which that youtube guy hadn't broken was the kingfisher "appalachian hickory", which is actually just shagbark/shellbark/bitternut hickory as I understand it. Awesome wood, not the hardest at all, but the right balance of properties for something you want to whack other things with.

I've tried doing White Oak with some of the MatLab info:

Code: [Select]
[IMPACT_YIELD:358050]
[IMPACT_FRACTURE:50000]
[IMPACT_STRAIN_AT_YIELD:3978]
[COMPRESSIVE_YIELD:358050]
[COMPRESSIVE_FRACTURE:50000]
[COMPRESSIVE_STRAIN_AT_YIELD:3978] bulk modulus 9 GPa
[TENSILE_YIELD:102300]
[TENSILE_FRACTURE:540000]
[TENSILE_STRAIN_AT_YIELD:842] young's modulus 12.15 GPa
[TORSION_YIELD:102300]
[TORSION_FRACTURE:11000]
[TORSION_STRAIN_AT_YIELD:2046]
[SHEAR_YIELD:102300]
[SHEAR_FRACTURE:11000]
[SHEAR_STRAIN_AT_YIELD:2046] shear modulus 5 GPa
[BENDING_YIELD:102300]
[BENDING_FRACTURE:50000]
[BENDING_STRAIN_AT_YIELD:842]

I've been curious looking at this again, does the Janka Hardness translate to anything in the DF material properties?

Found an interesting list while doing this, i'm going to post it here so I can remember:  http://www.woodworkweb.com/woodwork-topics/wood/146-wood-strengths.html

dwarf fortress doesn't actually have support for wood materials, in any meaningful way

there is correlation between janka hardness and tensile strength, but the only paper on that is $40

You can do some fun things with seasonal growths if you have the patience.  I made some giant mushrooms that change color every week, month or season, letting you determine the precise week in the year by looking at the caverns, kind of like a clock garden.
