Dear members,
I asked a question a year ago regarding using hyperelastic models
for soft tissue and am still getting inquiry for the answers. I am
posting a summary of answers. I want to thank people who provide me
feedbacks.

My question:
-----------------------------------------------------------------------

Dear group members,
I am working on modeling soft tissues (mainly live and breast) using
FEA. I intend to use a hyper-elastic material model, but it is hard
for me to find realistic parameters for these types of tissues. Did
anybody in this group have similar experience? Reference and
suggestions will be highly appreciated.
Thanks a lot!

I suggest you look at this one:

Miller, K. "Constitutive Modeling of Abdominal Organs", J.
Biomechanics., Vol.
33/3, pp. 367-373, 2000.

Cheers,
Karol

Jingfeng,
A couple of references that I have come across might be of interest to
you.

the pig kidney in relation with the biomechanical analysis of renal
trauma." Journal of Biomechanics 32(4): 417-25.

Dear colleague,

I am working on FEA soft tissue modelling too. Which code are you
using, abaqus, Marc..? And i have some experience on hyperelastic
modelling, mainly in ruberlike materials and heel pad's soft tissue.

I hope this reference will help you:

Azar,F.S. et al (2000) A finite element model of the breast for
predicting mechanical deformations during biopsy procedures. IEEE
workshop on Mathematical Methods in Biomedical image Analysis.( Hilton
Head, south carolina, June 2000)

There are too another interesting book:

Fung,YC. (1993) Biomechanics: mechanical properties of living tissues,
2nd edition, New-York: Springer verlag.

Best regards.
