Week 4- Rolling operation

Rolling operation

AIM

To carry out a static structural analysis on Rolling operation with given material.

PROCEDURE

To find and compare the results of Equivalent stress, Equivalent plastic strain, Directional deformation for the cases.

For this challenge, you will have to simulate the rolling operation on a workpiece made of copper. The model will be provided to you. Increase the length of the workpiece by 60mm and decrease its size on both sides by 8mm. Run the simulation for 14 steps and you can give small but random values( similar to the ones mentioned in the video) for the displacement. Ensure that the edge of the workpiece is displaced by 90mm.

Find out the

1. Equivalent stress for the whole setup
2. Equivalent Plastic strain for the workpiece
3. Directional Deformation in the Z axis for the workpiece
4. Prove that the workpiece has displaced by 90mm (Hint: It's mentioned in the video)

Import the model.

After import the model.

Assign the material as copper non-linear.

now structural steel material.

And copper as material for workpiece.

nd open the model panel.

In connection panel connect the wheel 1 and the oneside of the workpiece.

And another connection panel connect wheel 2 and other side of the workpiece.

contact size = frictional.

Frictinal co-efficient of 0.2

formulation = augmented tagrange.

interface treatment = add offset and ramped effect.

In joint load cylindrical

body-ground connection.

Another joint load cylindrical

body-ground connection.

create the mesh in the given component

Analysis setting

step = 14.

Large deformation = ON.

stabilization = constant.

Energy disstabilization = 0.1

Displacement.

joint rotation for wheel 1

joint rotation for wheel 2

Use solve for result

Equivalent stress for the whole setup

Equivalent Plastic strain for the workpiece.

Directional Deformation in the Z axis for the workpiece.

RESULT

Directional Deformation in the Z axis = 5.597MAX.

Equivalent stress for the whole setup = 2745.4MAX.

Equivalent Plastic strain for the workpiece = 1.2307MAX.

In workpice shape can be change.
