Week 4-1D Element Creation Challenge
1D Element Creation Challenge
AIM:
Take a mid surface & mesh the given component & create 1d element 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 model by using geomentry option.
As the thickness of the given component is uniform, midsurface is taken for the midsurface option.
After creating midsurface.
Creating a material and select the MAT1 for steel.
create the hyperbeam option.

Mesh the Given component with the Size of 5 Units. Create 1D elements on the following component with given cross-section and DOF
Create RBE2 element using in 1D module for the 1st hole and bottom & lock all 6 DOF in XYZ as mentioned for the first case.
Create RBE3 element using in 1D module for the 2st hole and bottom & lock all 6 DOF in XYZ as mentioned for the secound case.
Create RBE3 element using in 1D module for the 3st hole and bottom & lock all 4 DOF in XY as mentioned and Z should be free for the third case.
d. & e. Apply the mass of magnitude 10 with the RBE2 link.
Create the RBE2
f. Join the two components with Spring elements
RESULT
The model can be created with proper midsurface and meshed the with element size of 5.
Connection can be created with RBE2 and RBE3 element.
And created CROD, CBEAM, CBAR.
