Week 4-1D Element Creation Challenge

Objective:

To Mesh the Given component with the Size of 5 Units and to create 1D elements on the given component with given cross-section and DOF.

Procedure:

• At first import the given CAD model.
• Next delete the solids in the CAD model.
• After that use modsurface option to take mid surface from the model.
• After taking the midsurface for each of the bracket, allign the properties and mateials for each of the bracket as, Bracket-1, Bracket-2, Property-1, Property-2, Material-1, Marterial-2.
• After allighning the properties for the model, start meshing the model.
• Use 2D meshing, select auto mesh and mesh the complete model.
• Consider 1st hole as a-a, 2 nd hole as b-b, 3rd hole as c-c.
• Using RBE2/rigid connect a-a holes, by using RBE3 connect b-b holes, by using RBE3 connect c-c holes.
• USING MASS COMMAND ADD MASS INTO THE RBE2.
• After that use hyper beam command to ser the hyper beams,

  a. Rod element:- Translational DOF should be Constrained with RBE2 link

  Cross-Section: BOX- Dimension a= 12 mm

  dimension b=10 mm

  Thickness t= 0.75 mm

  b. Beam element:- All DOF should be constrained with 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:- Constrain only x and y DOFs With RBE3 link

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

  Thickness DIM2= 1.2 mm

  Dimension DIM3= 10 mm

  Thickness DIM4= 1.2mm.

• After alligning these values allign/update the properties of the elements.
• At last verify the model.

Conclusion:

The Given component is meshed with the Size of 5 Units and Createated 1D elements on the following component with given cross-section and DOF.
