Basis of the Load Duration Factor for Wood: Cd
(OP)
Does anyone know why wood is stronger with a shorter load? I imagine it has something to do with fibers breaking one by one under load, but I haven't found any references to explain the behavior.
Also, it seems that wood fatigues in deflection. That is, a bend will increase over time with a constant load. Why isn't E also time rated?

I'm curious about the actual internal mechanism for creep. What is happenning in the wood itself which causes it to creep? Also, is that creep still in the elastic range? That is, will the wood member recover fully when the long term load is removed?
