Week 4-1D Element Creation Challenge

REPORT

AIM:TO CREATE A MESH FOR THE GIVEN MODEL

CREATE BAR, ROD AND BEAM ELEMENT WITH DIFFERENT CROSS SECTION OF BOX,I AND X HAVING DIFFERENT DEGREES OF FREEDOM AND DIFFERENT DIMENSIONS.

STEP1:IMPORT THE CAD GEOMETRY.

2.SELECT GEOMETRY>MID SURFACE>SELECT ELEMENTS

3.CREATE BRACKET1 AND 2 FOR THE MID SURFACE.

4DELECT THE ENTITY AND MODEL AND DEFINE THE MID SURFACE WITH RESPECT THE FOLDERS NAMED BRACKET.

CREATE PROPERTIES FOLDER AND MATERIAL,SELECT STEEL AS THE MATERIAL AND DEFINE THE PROPERTIES OF THE MID SURFACE OF CAD MODEL AS STEEL HAVING PSHELL AND THICKNESS OF 2 AND 2.5 MM

CONNECT A WASHER AT THE HOLES OF 5 MM AND WITH OFFSET OF 0.3

MESH THE GIVEN SURFACE USING 2D AND AUTOMESH.GIVE THE MESH ELEMENT OF 5MM AND MANUALLY CHECK FOR ANY DISCREPENCIES.

CREATE RBE2 ELEMENT FOR THE HOLES USING RIGIDS

CREATE RBE 3 ELEMENTS USING RBE3 FROM 1D .FIRST SEKECT THE NODES USING MULTIPLE AND PATH OPTIONS.

USING HYPERBEAM CREATED THE I SECTION AND BOX SECTION AS PER THE GIVEN STANDARDS.THE PROPERTIES FOR ROD BAR AND BEAM HAS BEEN ASSIGNESD IN THE DROPDOWN LIST GIVING THE PROPERTIES AS PBAR,PBEAM AND PROD.

1 D REPRESENTATION OF THE BAR AND BEAM

2D REPRESENTATION OF THE MID SURFACE.

PROBLEM FACED

1THE X TYPE REPRESENTATION WAS NOT AVAILABLE IN THE HYPERBEAM OPTION SO IT WAS NOT CREATED.

CONCLUSION:

THE MODEL IS MESHED AND THE 1D ELEMENTAL ROD AND BAR WITH BOX AND I SECTION WAS CREATED.
