Abstract

FINITE ELEMENT ANALYSIS CARRY OUT THE QUASI STATIC RESPONSES OF FOAM-FILLED DOUBLE CIRCULAR TUBE IS PRESENTED IN THIS PAPER. IN THE INVESTIGATION OF THE CRASHWORTHINESS CAPABILITY, SOME ASPECTS WERE CONSIDERED FOR VARIATIONS IN GEOMETRY PARAMETERS OF TUBES AND THE LOADING CONDITION TO INVESTIGATE THE CRASHWORTHINESS CAPABILITY. EMPTY, FOAM-FILLED, AND FULL FOAM-FILLED DOUBLé TUBES OF THIN WALLED STRUCTURES WERE OBSERVED SUBJECTED TO OBLIQUE IMPACT (0Ë - 40Ë). THE NUMERICAL SOLUTION WAS USED TO DETERMINE THE CRASHWORTHINESS PARAMETERS. THE CRASH PERFORMACES OF FOAM-FILLED DOUBLE TUBE IS BETTER THAN THE OTHER STRUCTURES IN THIS WORK. THE OUTCOME THAT EXPECTED IS THE NEW DESIGN INFORMATION OF VARIOUS KINDS OF CYLIN-DRICAL TUBES FOR ENERGY ABSORBER APPLICATION.
