Interesting Biomechanics

Sorry David, don't take me seriously. I'm in a stupid mood and a bit wound up with work.

 

On topic however, It would be interesting to perform some tests on buckled and un-buckled wood of the same thickness and species.

 

The trouble would be developing a fair method that could be practically performed..

 

 

increment borer and fractometer. standard tools for that kind of work:001_cool:

But surely testing a core is not representative of the strength of a branch as you are only testing the wood perpendicular to the branch direction?

 

Forgive me if I have misunderstood, as I know very little of this type of subject..

 

I was thinking more of a practical test, anchoring two cut branches of the same diameter, one with fibre buckling one without and winching them both to failure and measuring which was strongest?

 

Or is that too subjective? Due to differences in the internal structure of each branch and different small flaws within the wood? I guess you would have to repeat the test 100s of times.. Interesting subject

 

I just want an excuse to snap some wood really

David, any scars or fractures within the crown?

 

I know this bet will be 20-30 years in the making but I know whos home here!

 

tbh tony, I haven't been up in the crown & from the ground there aren't any notable scars, fractures or cavities that I picked up on.

A good few tension cross overs.

 

This is in the woods, enough off the target track to not be in a risk zone.

Just kinda stumbled on it whilst out & about looking at stuff.

 

 

I've yet to come across cuticularis on any of these Beechin my ward, although it is in Kenwood on and around older generation trees.

 

But after having come across it fairly big numbers at Trent park a few weeks back on much younger trees, (& the ones that sean found on a young un at BB recently) I'm now often looking at trees of all ages for tell tale signs.

 

 

Guess I should be gettin on with me job really

youve been listening!

 

i dont think cuticularis is a big risk anyways, only about the same sort of level as fistulina in oaks, very low grade scenario in 99%.

 

I would swear on the oath thats whats causing these, saw the same today, and Im now very very certain of this language/decay association.

 

I think the wood will barely even show a discolouration at this stage, but a reckon a fracto and a microscope would tell different stories, to be further illustrated!

 

super bendy cores, and pitted lignin chimmneys !

Wow. What is going on there?? Someone please explain to me how stuff like that happens?

[sean freeman]

That is a beautiful piece of growth...what I would give to see a microtome through the tissues there....
