Step 2 Define Material Data
• Add the following Physical Properties by dragging and dropping them to the specified material
– Soda_Can and Soda_Can_Failure
• Density
• Isotropic Elasticity
• Bilinear Isotropic Hardening
– Soda_Can_Failure Only (additional)
• Plastic Strain Failure
– Water
• Density
• Isotropic Elasticity

Step 2 Define Material Data
• Return to the Project Schematic
• Save the project.
– Use the name “crush_soda_can”

Step 3 Import the Geometry
• Right-click on the Geometry cell to import the geometry file named “filled_soda_can.agdb”
© 2011 ANSYS, Inc. November 1, 2012 11
Step 4 Specify Materials
• Right-click on the Model cell and then Edit to open Mechanical
• Define the properties for Soda, Punch, and Die

Step 4 Specify Materials
• Define Soda Can properties
© 2011 ANSYS, Inc. November 1, 2012 13
Step 5 Specify Contacts
• Select Body Interactions
– Set Shell Thickness Factor to 1.0

Step 6 Mesh the Geometry
• Right-click on Mesh and then click on Generate Mesh
© 2011 ANSYS, Inc. November 1, 2012 15
Step 7 Edit Analysis Settings
• Specify End Time to 6E-4 s
• Change the Scope to Eulerian Bodies only (there is no need
to extend the Euler mesh to
cover the punch and die)
• Reduce the Total Cells from 250000 to 25000 (this is a
simple model, so a very fine
Euler mesh is not needed)

Step 8 Set Boundary Conditions
• Right-click on Explicit Dynamics to insert Fixed Support and then scope it to the Die
© 2011 ANSYS, Inc. November 1, 2012 17
Step 9 Set Boundary Conditions
• Right-click Explicit Dynamics to insert Displacement and then scope it to the Punch
© 2011 ANSYS, Inc. November 1, 2012 18
Step 9 Set Boundary Conditions
• Set up Displacement for X/Y/Z Components
• Enter Tabular Data as follows

Step 10 Define Result Set
• Right-click on Solution to insert Directional Velocity (Orientation: X Axis)
© 2011 ANSYS, Inc. November 1, 2012 20
Step 11 Run Explicit Dynamics
• Save the project
• Click Solve to run the Analysis
• Choose Solution Information to see progress
