Week 4- Challenge

OBJECTIVE: To create 1D elements on the following componenet with given cross-section and DOF.

Procedure:

1. To import the model from Import Solver Deck/Import geomentry/choose the file/click import.The model is imported.
2. Then have to create a midsurface by selecting the midsurface option from geomentry and select any one half of the bracket and extract.
3. Then select Features tree/Rename the middle surface as bracket 1 and change its colour and then create a component and change the name as bracket 2.
4. Follow the same procedure to create midsurface on the other side of the bracket.
5. Then use Tool/Organize/Surfs/select the above created midsurface/Move.
6. Delete the components of the both the brackets.
7. Create a material.Use Entities/Create/Material/Steel.
8. Now create property for both the midsurface and name it as bracket 1 and bracket 2.
9. Assign the corresponding property to the components.
10. Now do the autocleanup.
11. Create a washer split of offset value 5mm and split those circular areas.
12. Lets now mesh and assign element size as 5.
13. Now lets create 1D elements.
14. 1D/Rigids/Multiple nodes/calculate nodes/by path/Check dof 1,2 and 3/Create nodes around the circular Areas A.
15. 1D/rbe3/Check all dof/nodes/by path/create nodes in the area B.
16. 1D/rbe3/check dof 1 and 2/nodes/by path/create nodes around the circular area C.
17. 1D/rigids/Multiple nodes/Calculate nodes/by path/Check dof 3/Create nodes around the circular area D and E.
18. Now create a standard sections Box,I and Cross section.
19. 1D/Hyper Beam/Standard section/Standard I section/Create/Enter the dimensions given for beam element and rename the section as BEAM.
20. Create/Standard section/Optistruct/CROSS/Enter the dimensions given for bAR element and rename the section as BAR.
21. Create/Hyperbeam/Standard section/BOX/Enter the dimensions given for element and rename the section as ROD.
22. In the feature tree,create a property and name it as beam.Change the card image to PBEAM and select material as steel and choose beam section/BEAM.
23. In the feature tree,create a property and name it as bar.Change the card image to PBAR and select material as steel and choose beam section/BAR.
24. In the feature tree,create a property and name it as rod.Change the card image to PROD and select material as steel and choose beam section/ROD.
25. Now lets create CROD,CBEAM and CBAR elements.
26. 1D/rods/elem types as CROD/property as ROD/Select the nodes in region A.
27. 1D/bars/elem types as CBEAM/property as BEAM/select the nodes in the region B.
28. 1D/bars/elem types as CBAR/Property as BAR/Select the nodes in the region C.
29. Now lets create a MASS of magnitude 10 in region D and E.
30. 1D/masses/MASS=10/elem types as CMASS!/Select the nodes in the region E and D.
31. Lets create spring elements in the region F.
32. 1D/springs/elem types as CELAS1/Select the corner nodes on both side of the F region.

TOOLS USED:-

• Bars
• Rods
• Rigids
• Rbe3
• Springs
• Masses
• Hyperbeam
• Organize
• Midsurface
• Quick edit
• Autocleanup

RESULT:

The elements BAR ROD BEAM and Spring elements are created in the given component with the mentioned cross sections and DOFs using midsurface and meshing option.
