Mimics default empirical formular

Dear Mimics support team and users,

in some studies it is mentioned that they used “Mimics default empirical formular” for material assignment to the bone structure. I would like to ask if there is any reference for this empirical expressions?

for example:

Hi Iman!

In the latest Mimics Innovation Suite (version 26) user manual, you can find the origin of these empirical expressions. I’ve attached two screenshots - one of an example table and the other of the various studies from 1985-2002 used to formulate these expressions.

Hope this helps!

Thank you very much for the prompt reply.
In the user manual under “Material Assignment” section, and STEP D, it is mentioned: “STEP D: Choose to write out only the E-Modulus material properties in the exported file by deselecting the selection boxes before Density and Poisson Coefficient. We will use the following expression for the EModulus: E-Modulus = -388.8 + 5925 * Density”.
Many studies use this formula as Mimics default empirical formular. I could not find this in the Expressions tables. Is there any reference for this specific formula?
