Week 5 Sphere pressing on a plate

Objective: To perform the analysis to simulate a sphere pressing on a plate.

Procedure:

• Drop the static structural.
• From the Engineering data select the Non Linear static structural
• Import the model from library
• Open the Mechanical Module.
• Rename the Geometry
• Click on the connections and delete the default connections
• Right click on the Cotacts and add Manual contact region
• For the contact select the curved surface of the sphere
• For the target select the top surface of the plate
• Select the type as frictional
• Select the coefficient as 0.74
• Generate the default mesh
• For Analysis settings, let the steps be 4
• Solver type be direct
• Weak springs be off
• Switch ON the Large Deflection
• Insert the Fixed support for plate and select the base of the plate
• Insert the Displacement, select the top surface of the sphere
• Define the symmetric region

Directional Plastic Deformation:

Result:

Maximum Deformation is 0.32929 mm on the Plate

Conclusion:

When the sphere is pressed onto plate for 4mm the plate deforms for 0.32929 mm and Equivalent stress is 3307.1 MPa.
