Wood mechanicals

Any woodheads around ? :)
I made some testing for different samples of different wood materials, just for fun.
I measured damping curve for slender cantilever wooden beams, other end fixed, other triggered to free decaying vibration from known displacement. Measuring device was LDV with high enough sample rate to see up to third mode for every sample. Then I did 3-point flexural testing, I got just only two flexural specimens per each cantilever sample.
Ok, all this was fun, but now I wonder that would it have been cool to measure also flexural relaxation modulus for these wood samples.
Has anyone of You guys ever done this kind of triple treat for some materials system? Those references I found do nothing else but just start to bug me, and this was supposed to be fun, aagh :)
I think I would replay this series of tests with extended hassle (and this time I'll do things with equally conditioned samples between each tests. ..is this how scientists get started? I'm worried :)
Anyway, I'd like to figure out some more. Can You guys recommend some source reading for relations between damping and relaxation of wood materials? I know, visco and elastic behaviour are weighted very differently here like usually when comparing dynamical and nearly static test situation. I may ask thing as old as pinus aeternis (or homo dumbassius), but just because this bugs me, I dare to open my mouth here.
