Week 4-1D Element Creation Challenge

AIM:-

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

d. & e. Apply the mass of magnitude 10 with the RBE2 link

f. Join the two components with Spring elements

Objective:-

Mesh the component with the Size of 5 Units. Create 1D elements on the following component with cross-section and DOF.

Process:-

step one we will check topocleanup requirement and then extract mid surface from the component.
now as we know that we need to do meshing of the mid surface we will create a washer surface to the circles present on the mid surface in below as show in figures.
now we will provide 2D meshing to the component with a suitable target size
while meshing process we take care that there should not be any opposite trias,trias near-circular surface and tria on fillets.
as we know that wherever there is (a) point is mentioned we have to allot RBE2 element with only a translation degree of freedom.
wherever there is (b) point is mentioned we have to provide RBE3 link with all degree of freedom.
wherever there is (c) point is mentioned we have to provide RBE3 link with only X and Y degree of freedom.
we have done it by going to the 1D page selecting the option of Rigid and RBE3 respectively.
Then to create ROD, BAR, and BEAM we have to go to the hyper beam option.
now we will connect both brackets with a rod, bar, beam, and spring 1D element.
as you can see in the image we have connected two-bracket with the rod, bar, beam element with their respective dimensions.

conclusion:-

we understood how to allot 1D elements in terms of rod, bar, beam.we also understood the use and function of hyper beam.
