Week 4-1D Element Creation Challenge

AIM: For Given component create mesh with the Size of 5 Units and Create 1D element component with given cross-section and DOF.

model:

PROCEDURE: 1.Imort the model using import geometry which is in .iges format.click on import

2. creating the midsurfae using auto midsurf. Geometry>midsurface>automid>select the surf if the model.

3. assign the property and material to the created mid surface. Do the geometry clean up ,geometry>autocleanup>surf>create.

4. create the washer around the holes to get the good mesh flow .

5. mesh the whole compenent using automesh option 2D>automesh>element size>select the model>extract.

6. adjust the mest flow and give the rigid links at the hole create the RBE2 and RBE3 .1D>rigid>multi node>calculate nodes>path>element type>create.

7. create the rod element between the RBE2 links . 1D>rod>element type>node1>node2>select on center of the RBE2 links.

8.similarly , create beam and cross section links in the next two holes .

9. hyperview > rightlick >create>standard>hypermesh>I section /rectangle>given dimension>ok.

10. create the material and properties for each section. and update the each section by assigning the properties,basic section and material.

11.bea,rod,bar is created it is shown below

12. create RBE2 links at the edge holes and assign the mass at the links.1D>masses> element type >element size>property>create.

13. create the spring connections at the edges of the component, 1D> spring>element type>DOFs>select the nodes>create.

14. To view the beam ,rod go to the 1D detailed element representation .

conclusion: By this challenge i learned how to extract the mid surface and proper mesh flow with rigid links at the holes using different cross sections rod,beam,bar and assiging of masses at the links.

I learned and did my assessment on this topic within short period of time .
