In NX11 pre/post, I am using the "1D Element Section" mesh function to calculate the cross-sectional properties of an arbitrary shaped cross-section (i.e. random geometry) by selecting "Face of solid" as beam section type.
According to the Element Library Reference (Link), the mesh-based "Pilkey-method" is used to determine the cross-sectional properties of non-standard sections. (At least, I assume that the method is automatically used, since no hard-coded analytical equations exists for the arbitrary cross-sections).
My question is:
What equations are solved by the mesh-based "Pilkey-method" to determine the shear stiffness factors (K1/K2)? Or what theory is this method using to determine these factors?
Thank you in advance,
