Assignment 5-RADIOSS Interfaces & Study of Effect of Notches Challenge

OBJECTIVE : (1) CREATE MESH OF BUMPER ASSEMBLY WITH MESH THICKNESS 6 MM.

(2) IMPORTED 000. RAD FILE OF THE CRASH TUBE MODEL FIRST RUNS THE SIMULATION AS IT IS CALL IT AS CASE 1.

(3) IMPORTED 000. RAD FILE CHANGE THE INACTI = 6 IN TYPE 7 CONTACT RUN THE SIMULATION AND SAVE AS CASE 2.

(4) IMPORTED 000. RAD FILE CREATES TYPE 11 CONTACT AND RUNS THE SIMULATION.

(5) IMPORTED 000. RAD FILE REMOVES THE NOTCH AND REMOVES BOUNDARY CONDITION ON THE RIGID BODY THEN RUN.

(6) IMPORTED 000. RAD FILE CREATES A NEW NOTCH IN THE MIDDLE RUN OF THE SIMULATION.

(7) IMPORTED 000. RAD FILE CREATES A NEW NOTCH WITH ONLY OPPOSING 2 FACES AND RUNS.

PROCEDURE -: (1) FIRST I MESHED THE BUMPER ASSEMBLY OF EACH COMPONENT ONE BY ONE WITH ELEMENT SIZE 6 USING THE AUTO MESH OPTION IN 2D

(2) IN THE SECOND PART OF THE ASSIGNMENT WE WILL RUN THE CRSH TUBE ANALYSIS BY MODIFYING THE CONTACT TYPE, PARAMETERS, AND GEOMETRIC SHAPE THEN ANALYZE AND DISCUSS VARIATIONS IN THE RESULT.

CASE 1 - IMPORT "000.RAD" FILE GIVEN IN THE ASSIGNMENT GOES TO ANALYSIS > RADIOUS >SELECT THE LOCATION OF THE RESULT FILE EXTRACTION LOCATION AND RUN THE SIMULATION AND OBSERVE THE RESULT.

CASE 2 - IMPORT "000.RAD" FILE GO TO MODEL BROWSERS > GROUP > SELF CONTACT ( TYPE 7 )>INACTI = 6.

CASE 3 - IMPORT "000.RAD" FILE GO TO GROUP CREATE NEW CONTACT AS TYPE 11 SELECT > SELCET MASTER AS ALL COMPONENT AND SELECT SLAVE AS ALL COMPONENT. ISTIF- 4, IGAP- 1000, MINIMUM STIFFNESS 1, INACTIV -6, GAP MIN 0.4.

CASE 4 - IMPORT "000.RAD" FILE REMOVE NOTCH USING ALIGN NODE OPTION IN GEOMETRY> NODE EDIT AND RUN THE SIMULATION.

CASE 5- IMPORT "000.RAD" FILE CREATES A NEW NOTCH IN THE MIDDLE USING THE TRANSLATE OPTION IN THE TOOL TRANSLATE IT BY 5 MM INSIDE AND RUN THE SIMULATION AND OBSERVE THE RESULT.

CASE 6 - IMPORT "000.RAD" FILE CREATES A NOTCH ON TWO OPPOSITE FACES, RUNS THE SIMULATION, AND OBSERVES THE RESULT.
