Example8 Bar Fixed at Both Ends Subjected to Thermal Load

General

• A bar fixed at both ends is subjected to thermal load.
   

• The deformation, the displacement and the mechanical stress are solved.
   

• Unless specified in the list below, the default conditions will be applied.
   

Analysis Space

Analysis Conditions

The temperature is applied evenly on the model.

Opt for the thermal load in the analysis condition, and set the reference temperature and the reached temperature.

There is no need to couple with the thermal analysis [Watt].

The Step/Thermal Load tab is set as follows.

Model

The bar is a solid body made of copper. The face topologies of the both ends are fixed in Y direction.

Results

The vectors of the displacement are shown below. The color scale indicates the magnitude of the displacement.

The deformation is exhibited only on the XZ directions as the Y direction is fixed at the ends.

The vectors of the mechanical stress are shown below.

There are no stresses exhibited in the XZ directions as the bar can expand freely in those directions, whereas the tensile stresses are exhibited in the Y direction as it is fixed in that direction.

The external force and reactive force are listed in the table below.

The reactive force at FIX_Y1 is 71[N] in +Y direction.

The reactive force at FIX_Y2 is 71[N] in -Y direction.
