Goal:
– Perform a convergence study on contact stiffness
Steps to Follow:
If you already have Workbench open from previous workshop, start a new analysis with Utility Menu>File>New…
Browse for and open “W3a-stiffness.wbpj” project file.
The project Schematic should look like the picture to the right.
– From this Schematic, you can see that Engineering (material) Data and Geometry have already been defined (green check marks).
– It remains to set up and run the FE model in Mechanical
– Open the Engineering Data Cell (double click on it OR Right Mouse Button (RMB)=>Edit) to verify the linear material properties.
– You might have to activate important dialog boxes from Utility Menu > View >…
Properties
Outline
– Verify that the units are in Metric (Tonne,mm,…) system. If not, fix this by clicking on…
Utility Menu >Units >Metric(Tonne, mm,…)
Return to Project Schematic
– Utility Menu > Return to Project
Double click on the Model Cell to open the FE Model (Mechanical Session) (or RMB=>Edit…)
-Geometry is 2D Axisymmetric. Lower plate is rigidly constrained. Upper plate is a flexible body with a crowned contour along bottom face. The upper plate is under a 5MPa pressure load acting downward.
-Material: Both plates are default linear elastic structural steel.
A single contact pair has already been set up with the following specifications:
