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 ration, 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.
Beam Properties
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).
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 transfered 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.
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 transfered from a Beam interface or Pipe Mechanics interface.
