Week 4-1D Element Creation Challenge

Week 4-1D Element Creation Challenge

AIM:

To create 1D elements on the given component with given cross-section and DOF using Hypermesh

SPECIFICATION:

1. 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

1. 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 = 0.6 mm

Thickness t3 = 0.6 mm

1. 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

1. & e. apply the mass of magnitude 10 with RBE2 link
2. Join the two components with Spring elements

PROCEDURE

• After importing the model create mid-surface and mask the remaining surfaces.
• Assign the material and property for these surfaces.
• Then mesh the mid-surfaces with given element size of 5 units.
• Assign RBE2 and RBE3 links as per the given conditions and create Bar, Beam, Rod, Mass and Spring elements as per the given conditions.
• Apply material and property to these Bar, Beam and Rod elements and show the 3D view.

Conclusion

• Extracted the mid-surface for the given component and Created a Mesh on the mid-surface
• Deployed suitable 1D Element ( RBE2, RBE3, ROD, BAR, BEAM , MASS, SPRING etc ) to the respective places.
• Assigned Cross-section and property to the 1D elements
• Created Solid representations of 1D Element
