Ring Load
A load applied to a point, not located at the axis of revolution, in a 2D axisymmetric model actually represents a ring load. Add a Ring Load to points located at R > 0 to model such loads.
Force
Select the Load type — Force per unit length or Total force. Enter values or expressions for FL or Ftot.
•
The Load list normally only contains User defined. When combining with another physics interface that can provide this type of load, it is also possible to choose a predefined load from this list.
•
The Total force option should not be directly interpreted as a resultant, since the orientation is changing. Rather, it should be interpreted as the per unit length values, multiplied by 2πr, where r is the radius of the point.
Linear Buckling
To display this section, click the Show More Options button () and select Advanced Physics Options in the Show More Options dialog box.
If you are performing a linear buckling analysis with a combination of live and dead loads, select the Treat as dead load check box to indicate that the load contributions from this node are constant. The default is that a load is proportional to the load factor.
For more information about live and dead loads, see Buckling Analysis.

You can add the Phase subnode to specify the phase of this load in a frequency domain analysis.
•
You can specify this load to be a Harmonic Perturbation in a frequency domain analysis.
•
You can assign this load to a load group. See Load Cases in the Structural Mechanics Modeling chapter.
