Hello, please follow the link to see the diagram of the model. What I have are two simple bone blocks on the top and the bottom. At the inner surfaces of these blocks is a 0.5 mm partition of cortical bone, which is a higher modulus bone then the bulk of the blocks. In this "cage" device I have...
To give an update everybody, here is the link to the human vertebral body scan:

It is about 116 MB. I was wondering if anyone can offer help as to how to apply material properties like 12000 MPa to the cortical bone, 3500 MPa to the posterior elements...
Response from Robert via email (posts not on eng-tips because of file size issue, thus communication via email also):
I have only heard of relating bone density to material properties not element size. The shelling is traditionally for laminate structures such as carbon fiber over a foam core...
The previous links do not work. If anyone wants to help with these vertebral models, and add material and element properties, including posterior elements etc., that would be much appreciated.
Here is the updated link and download, the file is pretty large...
Much appreciated for the response. I will attach the IGS file for the L2-L3 motion segment.
If you have ABAQUS this would be very very helpful if you could do it in there, but SolidWorks would be great as well.
All of this is tricky, but more tricky than the skin is assigning material to the...
Hello - please I am looking for some help on how to partition bone, the spine in particular, and want to make for instance a cortical layer, a cancellous core, and also be able to make the posterior elements a certain material property. After this I plan on using meshes of varying density in the...
