Week 4- Challenge

OBJECTIVE-

To create 1D elements on the given component with given cross section and degree of freedom (DOF)

PROCEDURE-

STEP 1 . IMPORTING THE GEOMETRY

FILE -->IMPORT-->GEOMETRY-->(select file)--> import

STEP 2 -->

1.EXTRACTING MID SURFACE

GEOM-->MIDSURFACE-->AUTOMIDSURFACE(SKIN OFFSET)--->SELECT SURFACE-->SELECT TOP SURFACE

2. CREATE NEW COMPONENT AND RENAME IT AS BOTTOM_SURFACE

AND CREATE A NEW MID SURFACE

3.MOVING THE MIDSURFACE TO BOTTOM_SURFACE-->TOOLS-->ORGANISE-->SELECT SURFACE MOVE(MAKE SURE THE SELECTED COMPONENT IS BOTTOM_SURFACE)

STEP 3-->

1.DELETE SOLIDS AND ALL OTHER COMPONENTS EXCEPT MID SURFACES

GO TO DELETE-->CHOOSE SOLIDS-->DISPLAYED --->OKAY

2.ASSIGN WASHER SPLIT ---> 5MM --->AND SELECT ALL CIRCLES OR HOLES

STEP 4--> MESHING

GO TO 2D MESH --> AUTOMESH -->SELECT 8 MM MIXED AND MESH IT

STEP 5

CREATE RB2 RB3 AND RESPECTIVE RIGIDS

1D-->RIGIDS -->SELECT RB2-->SELECT THE RESPECTIVE NODES AND CREATE

SELECT RB3--->AND UNSELECT THE REQUIRED DOF -->CREATE

STEP 6---> CREATE BAR ,BEAM AND ROD ELEMENT

BAR--->SELCET TWO NODES ONE FROM EACH COMPONENT AND DEFINE THE VECTOR DIRECTION ELEMENT TYPE(CBAR)--CREATE

2.CREATING ROD --->SELECT ROD--->AND CLICK ON RESPECTIVE NODES WHERE BAR NEEDS TO BE CREATED AAND ELEMENT TYPE SELECT CROD

3.CREATING BEAM--->SELECT BAR --->SAME AS ABOVE AND SELECT CBEAM AND ASSIGN MATERIAL ,CREATE

4.CREATING MASS-->SELECT MASSES AND ADD NODES WHERE MASS TO BE APPLIED AND ENTER THE VALUES OF MASS -->CREATE

STEP 7

CREATING 1D MODELS

HYPERBEAM-->STANDARD SECTIONS-->CREATE

1.SELECT THIN WALLED SECTION -->GIVE THE RESPECTIVE DIMENSION AS SHOWN BELOW

2.SELECT I SECTION--->GIVE DIMENSION AS SHOWN BELOW

3.SELECT CROSS SECTION -->EDIT DIMENSIONS

1.

2. I SECTION

3.CROSS SECTION

ASSIGNING 1D

1.GO TO PROPERTY ASSIGN RESPECTIVE ELEMENTS AND UPDATE THE RESPECTIVE BEAM ,BAR,ROD TO OBTAIN 1D ELEMENTS

RESULTS

1.THE GIVEN GEOMETRY WAS IMPORTED AND MESHED

2. 1D ELEMENTS WERE CREATED WITH GIVEN DIMENSION AND DEGREE OF FREEDOM
