Week 4- Challenge

Creat 1D elements on the following component with given cross-section and DOF

a. Rod element:- with only translational DOF and RBE2 link

Cross-Section: BOX- Dimension a= 12 mm

dimension b=10 mm

Thickness t= 0.75 mm

b. Beam element:- with all DOF and RBE3 link

Cross-Section: I Section- Dimension a= 8 mm

Dimension b= 10 mm

Dimension c= 8.5 mm

Thickness t1= 0.75 mm

Thickness t2= .6 mm

Thickness t3= .6 mm

c. Bar element:- with only x and y DOFs With RBE3 link

Cross-section: CROSS section- Dimension DIM1= 5 mm

Thickness DIM2= 1.2 mm

Dimension DIM3= 10 mm

Thickness DIM4= 1.2mm

d. & e. apply the mass of magnitude 10 with RBE2 link

f. Join the two components with Spring elements

PROCEDURE

1. Open the hyperworks desktop 2020.
2. 
3. Impot the geometery.
4. If geometery is in wireframe then go to surface with hidden edges.
5. For creating the midsurface select the bracket_0 and click on the extract and rename as bracket_0.
6. Do the same for bracket_1.
7. After extracting select the all solids and delete the solids by using delete command.
8. After deleting the solids then go to tree and in tree select and right click if there are any remaining files and delete them.
9. After deleting the solids check there is no overlapping between surfaces or any multiple surfaces if there is any multiple surface then delete the extra surfaces.
10. For identification purpose we can change the colour of bracket surfaces.
11. Press f12 to mesh the surface for better results use the washer split command in geometery.
12. Give the element size 10mm. and mesh the file.
13. Go to 1-d tool bar select the rigid command to make rbi 2 element.
14. After creating the rbi 2 element create the rbi 3 element respectively. For creating rbi 3 element go to 1d tab and click and create the rbi 3 element.
15. After that go to tab bar and click right click on mouse and create a three properties with the name rod, beam and bar respectively.
16. After creating the properties go to 1 d tool bar again and click a hyper beam command and create the cross section for rod beam and bar according the given dimension in the objective.

16. After creating the cross section assign the cross section to the property respectively. After assigning the cross section go to 1d bar again.
17. Select bar command and update the element and create the respectively elements.
18. For seeing the cross section which were assign to the elements go to toolbar below in workspace and click the 1 d detailed view that will show the the cross section.
19. For creating mass again go to the same tool bar and select the command and give the magnitude of 10 and create the respective rbi 2 element.

20. After creating the mass go back to the 1d tool bar and select the spring to create a connection between surfaces.

CONCLUSION
