Column Beam with Contact

This simulation tutorial will guide you through:

  • Applying pressure and fixture boundary condition
  • How to set up contact interactions
  • Viewing the von Mises stress in the simulation results
Figure 1: Column beam 3D CAD

Import the CAD file

  1. From the Projects tab of the dashboard, create a new project.
  2. Select  Import 3D CAD.
  3. Select the Library tab, within OnScale Library select Column Beam.
  4. For Initial Contact, select Unbonded.

Assign a material

  1. Using either the Model  tree or the 3D viewer, select parts Column, Angle and Beam.
  2. Using the Material dropdown in the properties panel, assign Aluminium to these parts.

Turn on General Contact for sliding contact between Beam and Angle

  1. Select the Physics tab.
  2. In the tree, select Global Settings.
  3. In the properties panel select  Edit.
  4. Toggle on General Contact (Solver checks for all possible surfaces coming into contact during the simulation and enforces a sliding contact condition between those surfaces).

Add bonded contact between Column and Beam

  1. Select the Modeler tab.
  2. In the toolbar select  Interactions.
  3. Select  Contact in the toolbar to add a contact interaction.
  4. For Type, select Bonded.
  5. Ensure SIDE A is expanded, using either the Model  tree or the 3D viewer, select Column – Face 1.
  6. Expand SIDE B, using either the Model  tree or the 3D viewer, select Beam – Face 17.

Add bonded contact between Column and Angle

  1. In the toolbar select  Interactions.
  2. Select  Contact in the toolbar to add a contact interaction.
  3. For Type, select Bonded.
  4. Ensure SIDE A is expanded, using either the Model  tree or the 3D viewer, select Column – Face 1.
  5. Expand SIDE B, using either the Model  tree or the 3D viewer, select Angle – Face 9.

Add a fixture

  1. Select the Physics tab.
  2. In the toolbar select  Restraint to add a fixture.
  3. n the properties panel, set Type to Fixture
  4. Using either the Model tree or the 3D viewer, select the Column – Face 16.
  5. Select Done.

Add a pressure load

  1. In the toolbar select  Pressure to add a pressure load.
  2. Using either the Model tree or the 3D viewer, select the Beam – Face 0 which represents the location where the passenger would be sited.
  3. In the properties panel, for Pressure enter 20e3Pa and select Done.

Run a simulation

  1. Select the Simulator tab.
  2. Click on the Launcher to run the simulation.
  3. Once the meshing and estimation is complete, Select Launch to run the simulation.

Analyze the results

  1. Once the simulation has finished, select Open Results to open the results in the Results tab.
  2. For Ouptut Datasets, select von Mises.
  3. In the viewbar, select  Settings and toggle Show Mesh.
