Hello,
I have to assign properties to dorsal scapholunate ligament in the wrist. From literature I have only linear stiffness and recently published paper with tensile and torsional structural properties of the native scapholunate ligament where they list one figure of loading-unloading curve and the length of the ligament. Unfortunately, they do not provide cross-section area making it difficult to calculate stress-strain curve out of load-displacement.
What material model will you suggest to use in this situation?: Neo-Hookean, Ogden ....?
Maybe I can get material parameters via optimisation paper experiment?
