elastic constants/bulk and shear moduli for oak

elastic constants/bulk and shear moduli for oak

elastic constants/bulk and shear moduli for oak

(OP)
I'm undertaking a project using biot theory to model the velocity of compressional waves through wood 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.

RE: elastic constants/bulk and shear moduli for oak

if you could send me the type of wood that you are looking for i have a good source on here at my desk which will list the properties that you might be looking for....for example:

American White Oak
Data is based on small, clear, air-dried samples unless specified.
PHYSICAL PROPERTIES    
Density, g/cc    0.68        0.68 g/cc
MECHANICAL PROPERTIES    
Tensile Strength, Ultimate, MPa    5.5    transverse.    798 psi
Flexural Modulus, GPa    12.4    12.28-12.4 GPa in bending; 0.105 GPa Modulus of rupture in bending.    1,798 ksi
Flexural Yield Strength, MPa    56.5    MPa bending stress at proportional limit.    8,195 psi
Compressive Yield Strength, MPa    50    48.3-51 MPa axial (parallel to grain); 9.1 MPa transverse.    7,252 psi
Shear Strength, MPa    13.5    13.1-13.8 MPa    1,958 psi
CTE, linear 20ºC, µm/m-°C    4.9    axial. Typical value for Oak.    2.7 µin/in-°F
CTE, linear 20ºC Transverse to Flow, µm/m-°C    11.1    radial; 54.4 µm/m-°C tangential. Typical values for Oak.    6.2 µin/in-°F
            


RE: elastic constants/bulk and shear moduli for oak

Hii jj0508,

Can you give me the name of the source (I suppose a book) you have.  I am also dealing with physics of musical instruments.  So that I also need that kind of a book.

Thanks a lot

RE: elastic constants/bulk and shear moduli for oak

Well there is a web page that might help you as well...it will be a lot easier than trying to find this book (seeing as its SO old I doubt ANYONE else will have a copy)..SO try http://www.matweb.com/search.htm ;  (Hope that helps some)   

Jessica
