elastic constants for wood/ bulk and shear moduli
elastic constants for wood/ bulk and shear moduli
(OP)
I'm undertaking a project using biot theory to model the velocity of compressional waves through wood (oak) samples. However I'm having a hard time findig values for the elastic parameters such as bulk and shear moduli any help or data would be greatly appreciated.
cheers.

But... you may have to do some serious research yourself to determine the properties you want. Are you working on a Ph.D. dissertation? Sounds very interesting.

A good source for Young's modulus is the supplement to the National Design Specification. This gives E's in the range of 800,000 psi to 1,400,000 psi for Oak. The larger the piece being investigated the more variation in the elastic properties. If the specimen is relatively clear, the higher values of E may be used.
