Week 5 Sphere pressing on a plate

Objective:

• To perform the analysis to simulate a sphere pressing on a plate using Structural steel Non linear material of the plate.(Press the sphere onto plate 4mm downwards and retract it)

• And Find out the results for:

1. Plastic Deformation

Procedure:

Step 1: Engineering Data

• Add Structural Steel NL material to drop down list of materials.

Step 2: Geometry

• Right click on geometry and Import the Skill_Lync_Sphere_pressing on plate.step extension file
• Rename the Static Structural tab as Sphere Pressing Over a Flat Plate..
• update the Model tab and open click Edit.

Step 3: Model and Meshing

• Open Model and under geometry assign names according to convenience for better understanding.
• Rename geometries as Sphere and plate.
• Assign Structural steel NL material to Plate.

Step 4: Connections

• Contacts:- Define the contact faces between wheel and workpiece properly. Change type of contact to frictional in both cases.
• Change frictional coefficient to 0.74 using Augmented Lagrange as Formulation method.

Step 5: Setup

• In analysis settings select all 5 steps and switch on the large deflection in solver controls.
• Insert Displacement to Sphere body along Y direction defined by tabular data.(0,-2mm,-3mm,-4mm,0,0)
• Insert fixed load to bottom surface of plate.

• 
• It is important to define symmetric region around Z-direction and X-dir.(Nornal face dir) in this case.

Results:

Result and Conclusion:

• The Directional Deformation is 0.32634 mm (Maximum Value).
• The Equivalent Plastic strain is 1.6617 mm/mm
• Thus the simulation is successfully concluded using 4mm displacement and plastic deformation is captured.
