6.5 Solid Loads
Solid loads act on all 3D elements of a solid (see Chapter 4.5).
To apply a solid load, a solid must already be defined.
The number of the solid load is automatically assigned in the New Solid Load dialog box, but can also be changed there.
In the text box, enter the numbers of the solids on which the load acts. You can also select them graphically by using .
When you have selected the graphical input by clicking the toolbar button, you have to enter load data first. After clicking [OK], you can select the relevant solids one by one in the work window.
This dialog section is used to define the type of load. The following load types can be selected.
|Load Type||Short Description|
Solid load acting uniformly in one of the global directions
Uniformly distributed or linearly variable temperature change in the solid
Imposed tensile or compressive strain of the solid that is uniformly distributed or linearly variable
Weight of displaced material whose density can be entered or selected in a [Library]
Centrifugal force from mass and angular velocity ω on the solid
Additional forces can be applied on a solid in the form of surface or line loads.
The load can act on the solid as Uniform or Linearly variable. It refers to one of the global axes X, Y, or Z.
If linearly variable loads are selected, specify the load values of two nodes. Nodes are allowed to lie outside of the stressed solid, provided that FE nodes are generated there.
In this dialog section / these table columns, the load values and, if applicable, the assigned nodes are managed. The text boxes are labeled and accessible depending on the previously activated selection fields.
If linearly variable loads are selected, specify two nodes on which RFEM can determine the load magnitudes. These nodes are used to define a plane. You can also select them graphically using .
For a uniform load distribution, only one numerical value is required. For a linearly variable change in temperature or axial strain, specify two load values.
The graphics in the New Solid Load dialog box are useful when entering load parameters.
