Week 4- Challenge

OBJECTIVE:

Creat 1D elements on the following component with given cross-section and DOF

1. Rod element:- with only translational DOF and RBE2 link

Cross-Section: BOX- Dimension a= 12 mm

dimension b=10 mm

Thickness t= 0.75 mm

1. Beam element:- with all DOF and RBE3 link

Cross-Section: I Section- Dimension a= 8 mm

Dimension b= 10 mm

Dimension c= 8.5 mm

Thickness t1= 0.75 mm

Thickness t2= .6 mm

Thickness t3= .6 mm

1. Bar element:- with only x and y DOFs With RBE3 link

Cross-section: CROSS section- Dimension DIM1= 5 mm

Thickness DIM2= 1.2 mm

Dimension DIM3= 10 mm

Thickness DIM4= 1.2mm

1. & e. apply the massof magnitude 10 with RBE2 link
2. Join the two components with Spring elements

Note: Attached the hypermesh model files (.hm) with the challenge and all image in the word file submited

STEP-1: IMPORT GEOMETRY TO GRAFICS AREA

STEP-2: MID-SURFACE BRACKET ONE AND EXTRACT. RENAME THE COMPONENT AS BRACKET-1

.

STEP3: CREATE COMPONENT AND REPEATES STEP 2 FOR BRACKET 3

STEP 4: DELETE THE SOLID SURFACE FROM COMPONENT AND MOVE THE MIDSURFACE FROM ORGANISE TOOL TO BRACKET -2 AND DELETE THE MIDSURFACE TO FROM COMPONENT.

STEP:5 CREATE MATERIAL PROPERTY PROVIDE THE SPECIFICATION

STEP 6: ASSIGN PROPERTY TO BOTH THE BRACKETS

RIGHT CLICK THE PANEL AREA AND SELECT CREATE GO TO PROPERTY AND RENAME THEM AS BRACKET 1 AND REPEAT SAME FOR BRACKET 2

STEP 7: GO TO GEOMETRY GIVE WASHER SPLITS TO LINE BEFORE AUTO-MESHING THE SURFACES.

STEP 8: GO TO 2 D MESH AND GENERATE MESH

Creat 1D elements on the following component with given cross-section and DOF

1. Rod element:- with only translational DOF and RBE2 link

Cross-Section: BOX- Dimension a= 12 mm

dimension b=10 mm

Thickness t= 0.75 mm

STEP 9: SELECT THE NODES AT WASHER AT [A] AT BOTH BRACKETS AND CREATE RBE2LINK RESPECTIVELY WITH ONLY TRANSLATIONAL DOF FROM 1D TOOL BAR MENU

STEP10: WE NEED TO GO TO THE HYPERBEAM MENU TO PREPARE THE DESIRED ROD ELEMENT IN SHAPE OF BOX WITH SPECIFIED DIMENSION AND THICKNESS ON THE LEFT BOTTOM OF SCREEN

STEP11: GO BACK TO MODEL BY CLICKING ON THE MODEL OPTION ON THE LEFT PANEL AND SELECT THE ROD OPTION FROM 2D TOOLBAR MENU. THEN SELECT THE CENTRE NODES ON THE LINK ON BOTH BRACKET AND CREATE

STEP12: CREATE PROPERTY NAME ROD AND ASSIGN THIS TO BOX WHICH WAS CREATED IN STEP 10

STEP 13:

.

STEP14:

STEP14: CREATE ALL REQUIRED RBE3 LINK FOR B, C, D,

FIG :1 DISPLAY OF ALL DESIRED PLACES FOR ELEMENTS AS PER QUESTION

AFTER REPEATING SAME STEP FOR ALL THE ELEMENTS IN THE OBJECTIVE THE FINAL APEARANCE WILL BE AS FOLOWS

IN THE ABOVE MODEL RBE3 ELEMENT LINK WITH CMASS 10 IS GIVEN AT BOTH THE POINT [E] AND [D] OF THE BRACKETS AND ELASTIC ELEMENT FOR SPRING ALSO GIVEN AT POINT [F]

FINALLY AFTER SELECTING 1D DETAIL ELEMENT REPRESENTATION THE MODEL LOOKS LIKE THIS

COLOUR OF ELEMENT CHANGED FOR MORE CLARITY
