Ring Load
A load applied to a point, not located at the axis of revolution, in an 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.
•
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.
