sacro-iliac joint

[R Mail]

Dear members
I am developing a FEM(finite element model) for
analysing the displacement of the sacro-ilium joint subjected to different
loads.I am looking for some information about the stiffness matrix.The
one i found is a non-symmetric one.If any one has come across some useful
papers,books dealing with this please send me a mail.
Thank you in advance
