This is a simple expampe of a beam bending under terperature load. It illustrates the forward coupling between a heat conduction analysis (computing the temperature field) and a subsequent mechanic analysis computing the displacement field due to temperature loading. The first sequence step is used to create a linear temperature distribution over the thickness of the beam. In the second step this is applied as an input for thermal strain. Due to the chosen mechanical boundary conditions there are considerable thermal stresses.
To get familiar with the example
- study the trelis journal file
beam2D.jouto find out which regions are defined
- look into the simulation input
heat-mech.xmland go through the analysis steps
- run everything (e.g. using
run.sh) and open the output in ParaView
- load the paraview state file
Additionally you can modify the example to
- compute the von-Mises equivalent stress
- choose boundary conditions at the left edge which do not over-constrain the vertical displacement. How do the results change?
