Homogeneous Cross Section
Add one Homogeneous Cross Section node for every cross section to be analyzed. One Homogeneous Cross Section node is automatically added when the physics interface is created.
Material Properties
Enter the material properties, Young's modulus, E and Poisson's ratio, ν. The default is to take the values From material. You can also select User defined, and enter expressions for the material data manually.
Currently only the value for ν is used, and it only influences the detailed distribution of shear stresses caused by a transversal load.
Even though it is possible to override material data from this section, there would seldom be a reason to do it. The material data is part of the definition of the layered material.
Beam Properties
This section is only present in 3D, since in 3D the physics interface formally uses the layered technology. There is no need to make changes here.
Section Forces
If you want to perform a detailed computation of the stress state in a beam cross section, enter the section forces.
Enter values or expressions for the following:
•
Axial force N (SI unit: N).
•
Bending moment around 1-axis M1.
•
Shear force along 2-axis T2.
•
Bending moment around 2-axis M2.
•
Shear force along 1-axis T1.
•
Twisting moment Mt.
•
After changing data in this section, you do not need to compute the study for this physics interface again once is has been solved. It is sufficient to do an Update Solution to get the stress plots updated.
•
If this interface is referenced in a Beam–Beam Cross Section Coupling, the inputs in this section are not accessible, since the cross section forces are transferred from a Beam interface or Pipe Mechanics interface.
Twist
Enter a value or expression for the Axial twist, ϕxl. The twist is used in the computation of the axial warping displacement.
