I'm sorry to say that I don't have any new info. Plenty of my colleagues are stumped by this problem as well. -jester117

Link to new thread regarding anisotropic elasticity properties. https://www.physicsforums.com/threads/closed-form-equations-for-elasticity-properties-for-anisotropic-materials.778893/

Hi all, I'm wondering if anyone knows of a way to obtain elasticity properties (Ex, Ey, Ez, Gxy, Gxz, Gyz, vxy, vxz, vyz) from the terms of a 6x6 anisotropic stiffness or compliance matrix. I'm looking for a closed form solution, preferably. I would think that there should be a closed form...

Thank you for the nudge, haha. I do have additional information. The problem I was having was concerned with the rotation of a 6x6 stiffness matrix for 3D stress-strain vectors. The coordinate transformation through Euler angles and the corresponding DCM generated were both correct (i.e...

Hi all, I'm looking for physical and mathematical explanations for a phenomenon I've noticed when working with rotated material properties relative to an XYZ coordinate system. For certain rotations (~40 to ~50 degrees) about a single axis the S12, S13, or S23 components of the compliance...
