How to convert a transversely isotropic material to an orthotropic material Here's a little problem that customers run into every once in a while and a way to get around one of Creo Simulate's limitations. Suppose you have a laminated composite with a quasi-isotropic layup (say, [0/+-45/90/90/-+45/0]) and you know only its equivalent smeared properties, which are equivalent to a transversely isotropic material. Or perhaps you have some other material that is transversely isotropic. Now suppose you want to assign that material to a shell idealization with the unique direction normal to the shell. How do you do that? Unfortunately, it's not as easy as it should be. When specifying a transversely isotropic material on the material definition dialog, the unique direction is the 1 direction and the plane of isotropy is the 2-3 plane.Figure 1To specify how this material is aligned in your model, you need to define a Material Orientation. The 1, 2, and 3 directions of the material orientation correspond to the 1, 2, and 3 directions of the material. However, for mate
