It is possible to get comparative results, but you have to be very careful about how you do it. The problem with the static test is that the longer you leave the load on, the greater the deflection you get, due to the visco-elastic behaviour of wood, leaving you with a decision as to when to take t...

I’ve been testing all my top and bracewood to find the best combination of stiffness and density, optimize plate thickness, etc. I started using the frequency-based method from the Gore books, but since I was also testing deflection, I decided to compare the flexural modulus using that method (also ...
