The mechanical properties of human cartilage

[Ibrahim Mutlu]

Hello,

i try to prepare experimental setup for my dissertation thesis in Kocaeli University. I am getting ready to anatomical models for compression test. I have patient-custom-made pelvis model using rapid prototyping methods. I intend to add a material that represents acetabulum and femur cartilage soft tissue. I have a thermo set material list and its material mechanical properties such as hardness (shore A, D), tensile strength and elongation. So I need the mechanical properties of human femur and acetabulum cartilage but many papers or sources don’t have any information about these properties. Therefore i am checking with the community to see if anybody knows these information or shows a source and paper.

Thanks in advance for your help

Re: The mechanical properties of human cartilage

I am surprised that you have not been able to find mechanical properties of cartilage. It seems to be a rather large field. Perhaps this may help spur your research: http://www.ncbi.nlm.nih.gov/pubmed?term=grodzinsky+a

Prof. Grodzinsky has done a lot with characterization of cartilage properties.

Re: The mechanical properties of human cartilage

Be aware that cartilage is a complex material (i.e., transverse isotropic, viscoelastic, and nonlinear depending on the load level and direction) and the characterization of mechanical properties of biologic materials is not a trivial task. Therefore, the literature presents with a wide range of values for the same material, depending on the experimental procedure. Moreover, the constitutive equation used to render the results may also not be the same.
