I'm trying to model a composite structure with shell 99 element in Ansys.
I set the thickness and material no. in real constant and prepare an orthotropic material property for that. While ploting the result, as I expect to get the stresses among layers different from other points, but the result is a kind of uniform isotropic graph.
I don't know if any setting other than real constant and material property should be done to get a true result or not. and if I'm true then how can I read the true result.
I will appreciate any help.
Thanks in advance.
