Week 4-1D Element Creation Challenge

PROCEDURES:-

Importing the geometry into the workspace by Import geometry option and deleteing the wire frame

By selecting the geometry top part and bottm part creating the mid surface on both top and bottom side of bracket.

Now assigning the material and its property on the mid surface of components.

Once the property and material assigned, we will create washer split and create mesh using command automesh in 2D while keeping the target element size of 5mm with mixed element type.

Now we will create the RBE2 element using rigid in 1D Module for the first hole in Top & Bottom, we also restrict the element to transitional DOF in X,Y & Z axis as Mentioned for the first case.

We will create RBE3 element using rigids in 1D module for the second holes in top and bottom, We will restrict the element to all DOF inX,Y and Z Axis as mentioned for the second case.

We will create RBE3 elements using rigids in 1D module for the third hole in top and bottom, we will restrict the element to all DOF in X & Y Axis for the third case

Once RBE2 & RBE3 created, we should create mass with the magnitude of 10 and type of mass should be given as CMASS and we create hyperbeam for Rod,Bar & Beam.

Now we will create cross section for Rod, Bar & Beam.
We will create cross sections for the rod in the form of thin wall box which has been given for the first case.

We will create cross section for the beam in the form of I-Section which has been given for the second case.

We create cross section for the bar in the form of cross section which has been given for the third case.

Once cross sections are created, we need to create property for rod,beam and bar with property card such as PROD,PBEAM & PBAR.

Mass is applied with the magnitude of 10 in RBE2 and Spring elements are joined as been mentioned.

Conclusion:-

The model has been imported & Mid Surface is taken for the given components & material property has been assigned.
We have meshed the components & holes has been connected with RBE2 & RBE3 elements.
Then we created CROD, CBEAM, CBAR 1D elements with their DOF constrained according to details provided.
Created cross sections of Rod, Beam & Bar, properties of card been assigned for PROD, PBEAM and PBAR.
The mass has been applied with the magnitude of 10 on RBE2 & Spring Elements are joined.
