Week 4-1D Element Creation Challenge

Question:

Objective:To mesh the given component with size5 units.

Procedure:

• Import the iges file by going to import geometry.
• start with midsurface by selecting each solid, organize the components as Bracket_1 and Bracket_2.
• create material as steel and properties with thickness of 5units, card image as PSHELL.
• assign the material and properties to the components.
• start with meshing the midsurface with 5units ,keep connectivity , start with the holes by adding a washer split to each holes.
• After meshing go to 2D detailed element representation to obtain the required mesh click on shaded elements and mesh lines to obtain the required mesh.

Result:

LEARNING: Creating midsurface, organizing,Washer split use etc mentioned in details in procedure.

A:Rod element

Objective:Translational DOF should be Constrained with RBE2 link for the rod elements with provided cross-section of box type.

Procedure:

• Go to rigids, select the nodes by window and create rbe2 elements by ticking dof1,2,3 to get the rbe2 translational only.
• Go to Hyperbeam,select standard section library as Hyperbeam , thinwalled box type and select the cross-section.
• create a property for box rod, and assign it the beam cross section and the card image.
• Now go to rods ,select the 2 nodes ,select the property ,select create ,shows cweld change it to CROD and update to get the 1-d Rod element.

B:Beam element

Objective:All DOF should be constrained with RBE3 link with provided cross-section.

Procedure:

• Go to rbe3, select the nodes by window and create rbe3 elements by ticking dof1,2,3,4,5,6 to get the rbe3 constrained.
• Go to Hyperbeam,select standard section library as Hyperbeam , I section beam type and select the cross-section.
• create a property for I beam , and assign it the beam cross section and the card image.
• Go to bars and select Cbeam,select nodes and create the beam element.

C:Bar element

objective:Constrain only x and y DOFs With RBE3 link and for the provided cross-section for bar element.

Procedure:

• Go to rbe3, select the nodes by window and create rbe3 elements by ticking dof1,2 to get the rbe3 constrained.
• Go to Hyperbeam,select standard section library as optistruct , cross type and select the cross-section.
• create a property for cross bar, and assign it the bar cross section and the card image.
• Go to bar,select nodes give direction and tab or middle mouse to create CBAR.

D&E: Mass

Objective:Apply the mass of magnitude 10 with the RBE2 link at the given location.

Procedure:

• Go to rigids, select the nodes by window and create rbe2 elements by ticking dof to get the rbe2.
• Go to mass and select the location and add the mass of magnitude 10.

F: Spring element

Objective: Join the two components with Spring elements

Procedure:

• select the nodes on both the bracket to create the spring elements.
• also you can go to connectors and spot to select mutiple nodes at a time.

Final result:

LEARNING: creating 1D elements such as bar,beam,rod,mass,springs and different hyperbeam options and the use of tools, detailed explaination is provided in the procedure.
