Week 4-1D Element Creation Challenge

AIM

------------------------------------------------------------------------------------------------------------------------------------------

• Mesh the given components by using 5 units.
• Create 1D elements on the following component with given cross section and DOF.

1. ROD ELEMENT: Translational DOF should be constrained with RBE2 link

Cross section:”BOX” a=12mm

b=10mm

t=0.75mm

1. BEAM ELEMENT: All DOF should be constrained with RBE2 link.

Cross section: “I” a=8mm

b=10mm

c=8.5mm

t1=0.75mm

t2=0.6mm

t3=0.6mm

1. BAR ELEMENT: Constrain only X&Y DOFs with RBE3 link

Cross Section: “X” Dim1=5mm

Dim2=1.2mm

Dim3=10mm

Dim4=1.2mm

1. Apply mass of magnitude 10 unit with the RBE2 link.
2. Apply mass of magnitude 10 unit with the RBE2 link.
3. Join the components with spring elements.

OBJECTIVE

------------------------------------------------------------------------------------------------------------------------------------------

• Check for geometrical errors
• Generate mid surface.
• Mesh by using 5 units elements size.
• Create 1D ements.

GEOMETRY CLEANUP

--------------------------------------------------------------------------------------------------------------------------------

Auto cleaned the geometry firstly for avoiding errors.

MIDSURFACE

--------------------------------------------------------------------------------------------------------------------------------

Generate the mid surface of the geometry.

Meshing

------------------------------------------------------------------------------------------------------------------------------------------

Mesh the components by using element size of 5 units.

1D Elements

------------------------------------------------------------------------------------------------------------------------------------------

Created the 1D elements according the given dimensions.

CONCLUSION

------------------------------------------------------------------------------------------------------------------------------------------

Hence all the process is done according to the direction.
