Week 4-1D Element Creation Challenge

DESCRIPTION:

1D ELEMENT : All line element, whether straight or curved, are called 1D element in which they have translational and rotational displacemnet function, examples 1D element are truss element. 2D elements are typically surface with triangle or quadrilateral as their basic shapes.

PROCEDURE

Import the model by using geometry option in the from of IGES format

As the thickness of the given component is unifrom , the midsurface is taken for the whole model.

Then we assign the material and properties to the midsurface component in the model browser.

Once material and properties are assigned ,we are meshing the compoent, by using automesh option in 2D and atrget element length should be 8mm then we create washer split surface for the holes.

We create RBE2 elements using rigids in 1D module for the first holes in top and bottom and we restrict the element to transitional DOF in X,Y,Z axis as mentioned for the first case.

We create RBE3 elements using rigids in 1D module for the first holes in top an dbottom and we restrict the element to all DOF in X,Y,Z axis as mentioned for the second case.

We create RBE3 elements using rigids in 1D module for the first holes in top and bottom and we restrict the elemnet to all DOF in X and Y axis as mentioned for the third case.

Once RBE2 and RBE3 create, we should create mass with the magnitude of 10 and typs of mass should be given as CMASS1 and we create hyperbeam for rods, bar and beams.

Then we create cros section for Rod , Bar & Beam

We create cross section for the rod in the from of thin wall box which has been given for the first case.

We create cross section for the Beam in the from of I-section which has been given for the second case.

we create cross section for the beam in the from of cross - section which has been given for the thirds case.

Once cross section are create , we need to create property for rod, Beam, bar with property cards such as PROD,PBEAM,PBAR

Mass is applied with the magnitude to 10 in RBE2 & spring element are joined as been mentioned.

Results:

. the model has been imported & mid - surface is taken for the given components 7 material property has been assigned.

. We have meshed the component and holes has been connected with RBE2 and RBE3 elements.

. then we create CROD, CBEAM, CBAR 1D element with their DOF constrained accoeding to the data has been mentioned.

. We create cross sections for ROd, BEAM, BAR and propertiey cards has been assigned for PROD, PBEAM, PBAR

. The mass has been applied with the magnitude of 10 on RBE2 & spring elements are joined.
