Week 4-1D Element Creation Challenge
objective:
to make midsurface from the given model,mesh it,make rod,bar,and beam with given details create rbe2 elements in the holes as per the given data.
Mesh the Given component with the Size of 5 Units. Create 1D elements on the following component with given cross-section and DOF
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
procedure:
import the given model after opening hypermesh.
now create midsurface.
after creating midsurface mesh it with 5 units.
given washer split to all holes in the model to create good mesh flow around holes.
now rbe2 links as per the given details in the question.
give the dof as per given in the question.
now create rod,beam,bar element's cross section with hyperview
the cross section are
a. 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
the masses should be added by masses in geometry tab.
spring elements should be given by constraining except translational y dof.
this image is the final image doing as per the procedure,the rod, beam, bar appears as line.
after giving 1d detailed appearence.
this is the final image of working as per procedure.
