Constitutive Matrix Transformation from Elemental Stiffness matrix
Hi all,
I am attempting to use a Nastran output elemental stiffness matrix and transform it into an MBDyn beam element constitutive matrix for a fully-coupled anisotropic beam. This practice is simple for isotropic beams, but the transformation has proven to be much more complex for a beam with complex geometry and coupling. Has anybody gone through this exercise before? Is there a well-known transformation matrix or method that I am missing?
Thanks,
Connor
