Properties defined in this condition are similar to that of the shell condition. The difference is that the material is orthotropic. The orthotropy axes are the ones defined in the Local axes field of the condition. The properties to enter are the Young Modulus (Ex, Ey), the Poisson coefficients (nuxy, nuyx) and the Shear modulus (Gxy, Gxz, Gyz). They are all referred to the local axes X' and Y'.
Note: Remember that to maintain the elasticity hypothesis it is necessary to accomplish that:
Ex· nuxy= Ey· nuyx |
Default units for E and G are N/m2 and nu is adimensional.
Remember that for an isotropic material:
For and orthotropic material:
