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, Force per unit area, or Total force. Enter values or expressions for FL, FA, or Ftot.
Moment
Select the Load type — Moment per unit length, Moment per unit area, or Total moment. Enter values or expressions for ML, MA, or Mtot.
•
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 and Total moment options should not be directly interpreted as resultants, 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.
