week-11 Joint creation and Demonstration

Case 1: REVOLUTE JOINT FOR RIGID BODIES:

1. create 4NShell elements as per shown below image.

2. create MAT and section cards.

3. Apply part.

4. create 4 nodes between two shell elements. As per the below image.

5. creat CONSTRAINED_NODAL_RIGID_BODY.

Join (73,31,32,33)(74,34,35,36)(75,40,41,42)(76,37,38,39)

Then transform (73,76)and(74,75)

6. Make SPC for BOUNDARY as per the below image.

7. Make BOUNDARY_PRESCRIBED_MOTION_NODE.
8. 

8. CONSTRAINED_JOINT_REVOLUTE.
9. creat load curve and database save the file.
10. Run ls dyna

JOINT_TRANSLATIONAL

1. create a Box shell and delete unwanted elements as per the below image.

2. Assign, MAT, section, part, database, and define curve as per the above model.

3. Assign SPC as per the below image.

4. Apply CONSTRAINED_NODAL_RIGID_BODY.

Make CNRB 3location for the outer shell and 3 CNRB for the inner location.

As per the below image.

5. Make constrained joint Translational as per the below nods.

6. Apply velocity as per the below image.

7. Save and run ls Dyna.
