Body Load
Add a Body Load to boundaries for modeling general volumetric loads.
For loads caused by gravity or rotation, it is more convenient to use the Gravity, Linearly Accelerated Frame, and Rotating Frame nodes.
Shell Properties
Select the layer or layers to which this load is to be applied.
Table 6-46: Layer Selections; Body Load.
Selection
Use All Layers
Selection of Individual Layers
Boundary
Same as interface selection when the node is added.
When Use all layers is not selected.
Only a subset of the layers selected in the interface can be selected.
Coordinate System Selection
The Coordinate system list contains all applicable coordinate systems in the model, including the Boundary system and the Layer local system. The Global coordinate system is selected by default. Body loads are specified along the axes of the selected coordinate system.
Contributions from several Body Load nodes having a common selection will be added to each other.
•
See Defining a Layer Local System in the Composite Materials Modeling chapter.
•
All other settings are described in the documentation for Body Load in the Solid Mechanics interface.
•
For a general description of layer and interface selections, see The Shell Properties and Interface Selection Sections.
•
You can prescribe loads with through-thickness variation by explicitly or implicitly using expressions containing the extra dimension coordinate as described in Using the Extra Dimension Coordinates.
•
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.
