WebYou can draw a diagonal down this matrix and the elements on either side will be equal, hence it’s symmetric. I think the one thing you might be missing, is that orthotropic materials are not the same as anisotropic materials. Built into orthotropy is the assumption that along an axis, the stiffness (or compliance) remains the same.
