Week 4- Rolling operation

Rolling operation 

Objective: 

To stimulate the rolling operation on a work piece of a copper material and to determine equivalent stress and equivalent plastic strain. 

Procedure: 

Importing the given component and assigning Copper NL material.

 

We need to modify the geometry by increasing the workpiece to 60mm. And reducing the faces by 8mm on both side. 

Now we have to give a contact between wheel and the workpiece, a revolute joint is assigned to the rollers 

A displacement condition is given to the workpiece with 14 steps. 

Both the rollers which are getting contact with the workpiece are said to be fictional with frictional coefficient of 0.2.

 

A mesh of 4mm is applied to the workpiece and then mesh is generated. 

Results:  

Equivalent stress for the whole setup 

Equivalent plastic strain for the workpiece 

Directional deformation of the workpiece in Z axis 

Directional deformation of the workpiece on Y axis
