Week 4- Challenge
Week 4 Mid surfacing and 1D elements:
Overview:
This is a report on Week 4 challenge of the Hypermesh for FEA Plastic and Sheet Metal Applications course.
Model:
Objective:
To create 1D elements in the given Bracket model with the specified cross sections and Degrees of Freedoms.
Given Model:
Procedure:
1. Import the IGES Bracket file into Hypermesh.
2. Create Mid surfaces of the top and bottom solid components separately with the help of midsurface panel in Geometry tools menu and create new components named as Bracket1 and Bracket2.
3. Create washer spilt on all the holes.
4. In 2D main menu, select automesh panel and generate a mixed type mesh of small element size say 6.
5. Select the nodes around the holes and the washer splits and create rbe2 and rbe3 elements with the specified Dofs in the 1D menu.
6. Create 2 CMASS1 mass elements of magnitude 10 with the help of masses panel at e and d holes.
7. Create 2 CELAS spring between 2 nodes in the top and bottom mesh at either sides of the model at f.
8. Select HyperBeam panel in 1D menu, select standard section radio button, select HYPER BEAM section library and select thinwalled box section and click on create button.
9. Specify the dimensions of the cross section in the HyperBeam view and rename as rod_element.
10. Right click on the Entities area to create similar cross sections like I-section and Cross sections and specify their respective dimensions.
11. Create properties for the elements and specify their respective card image and beamsec property from the list of sections already created.
12. Update the properties of rod, bar and beam element with their respective properties.
13. Click on 1D detailed element representation to view the elements with their cross sections.
