Workbench-Mechanical Contact Stiffness Study

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:
