The software considers thermal effects for buckling studies. Slender parts subjected to temperature rise, like electronic components, can buckle due to restrained expansion.
You can specify a uniform temperature rise, assign different temperatures to different regions in the model, or import a temperature profile from a thermal study.
When using the Input
temperature option, make sure to specify temperatures on components
or shells. Specifying temperatures on the boundary only may not be practical.
You may need to create and solve a thermal study first to compute temperatures
at all nodes.
To include thermal effects for a buckling study:
In the COSMOS AnalysisManager tree, right-click the buckling study icon and select Properties.
The Buckling dialog box opens.
Click the Flow/Thermal Effects tab.
Under Thermal options, select one of the following options:
Input temperature. Uses the prescribed temperatures defined in the Load/Restraint folder of the study to calculate their effects on the buckling of the model.
Temperatures from thermal study. Uses a temperature profile resulting from a completed thermal study. The thermal study can be steady state or transient. If you check this option, you need to specify the Thermal study. And if you select a transient study, you need to specify the Time step.
Temperature from COSMOSFloWorks. Reads the temperature profile resulting from a completed COSMOSFloWorks on the same configuration from a file. Browse to select the FloWorks Result Files (*.fld).
Set Reference temperature at zero strain.
Click OK.
