Orthotropy describes directional material properties. Beispiele sind faserverstärkte Kunststoffe, Trapezbleche, bewehrter Beton oder Holz. As a rule, Hooke's material law is not valid for orthotropic materials anymore.
Material Parameters
For a 2D shell element, the material parameters are as follows:
|
Stiffness in the local x-direction of the surface |
|
Stiffness in the local y-direction of the surface |
|
Shear stiffness in the local x-direction of the surface |
|
Shear stiffness in the local y-direction of the surface |
|
Shear stiffness in the panel plane |
