Specification of anisotropic material data of pipe (Input Table)
Through the input data table ANTROP the mechanical properties of anisotropic pipe material are provided.
The pipe material may vary along the pipeline. There is no direct relation between Emod, Gmod and Nu (Poisson ratio), so all values must be given. The distinction between E-axial and E-circumferential influences the bend stiffness factor in Design Function 5 and the bend stress distributions in Design Function 6.2.
In Design Function 6.2 the 'beam' stresses are calculated with Emod-NX and Emod-MX and the 'ring' stresses with Emod-NF and Emod-MF.
