Constructing a Stiffness Matrix for Research on Rat Scoliosis

[shwin]

Hi all,

I am doing a research project on how vertical tractional forces (applied at the tail of rats) affect scoliosis. I know the lateral deviations for each weight at specific columns of the spinal cord...however, I want to assess the lateral force at each specific point due to the vertical force applied at the tail. To do this I obviously need a stiffness matrix...how do I go about constructing one? Better yet, how can I use the data I have to create it?

Thanks in advance for any feedback.

any ideas?
