Week 4-1D Element Creation Challenge

Objective:

Introduction:

1D elements can be applied to 2D and 3D model by analyzing the indiviual line element that form the model's infinite element mesh .
1D elements are useful for stimulating how different section of the mesh will react to certain condition
1D elements are basically line shaped element which are created by two nodes
Example of 1D elements are RBE2,RBE3,ROD,BAR,BEAM,SPRING element

Procedure :

Initially the given model imported as per standard
Using the midsurfacing option midsurface created for each component ( to convert the 3D component to 2D shell component )

To creating material property for given component as Steel and its updated ( since no any material type mentioned )
start to automesh for given component while selecting all the surface . before the mesh create Washer split provided for each hole area
Mesh element size are 5 unit with mixed elements. Element size adjusted to improve the mesh quality in hole area.
Rod element ( at A )

In 1D menu creating a rigid element link (RBE2 Link ) at A with help of rigid element option . And , Translation DOF constrained with RBE2 link.

Rigid element created as CROD at A and Cross section has been created using hyperbeam option as per given dimension.

Property for ROD element created and updated .

Same as Rod element here RBE3 link created at B with help of RBE3 option. And, all DOF constrained with RBE3 link.

RBE3 element created as CBEAM at B and cross section has been created using hyperbeam option as per given dimension.

Property for BEAM element created and updated .

Here RBE2 link created at C with help of rigid option . And , X and Y DOF only constrained with RBE2 link

Rigid element created as CBAR at C and cross section has been created using hyperbeam option as per given dimension.

Property for BAR element created and updated.

Here RBE2 link created at D & E with help of Rigid option. all DOF constrained with RBE2 link.

Element created as CONM2 at D & E area and mass applied with magnitude of 10

Here spring element has been created with help of spring option at F section

Result:

ROD element as given dimension with RBE2 link created and Translational DOF constrained with RBE2 link successfully at A section
BEAM element as given dimensionn with RBE3 link created and all DOF constrained with RBE3 link successfully at B section
BAR element as given dimension with RBE2 link created and X and Y DOF constrained with RBE2 link successfully at C section
Mass has been applied with magnitude of 10 successfully at D & E section.
Joining the two components with spring elements created successfully at F section
