Week 4-1D Element Creation Challenge

OBECTIVE :

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:

Improt the CAD model
Extract the mid surface in CAD model by removing solid with adding wacthers as shown below

Create RBE2 with constraining translationa; DOF for rods. Create RBE3 for both bar and beam element with constraining X & Y DOF for bars and constrain all DOF for beam elements as shown below.

Apply the mass of magnitude 10 with the RBE2 link and Join the two components with Spring elements.

Upload the material,properties and cross section dimension for rod,beam and bar as per given in question.

CROSS SECTION DIMENSION & PROPERTY VALUE FOR ROD

CROSS SECTIION DIMENSION & PROPERTY VALUE FOR BEAM
