This final project is studying about energy absorption of thin-walled aluminum tubes with oval holes trigger using numerical method. The tube made of aluminum with 60 mm and 100 mm diameters and each has 2 oval holes trigger at the bottom part. The oval holes are introduced in the tubes to force plastic deformation to occur at predetermined intervals along the tube. The aims are controlling the buckling mode and predicting energy absorption capacity of the tubes. The tubes and quasi-static longitudinal load are modeled using ABAQUS, a finite element based software, and then the result data are studied and compared with experimental method and analytical method. From the compared result, it’s found that the load-displacement plot’s and the amount energy absorbed are quite similar. <br />

This final project also provides comparation between thin-walled aluminum tubes with oval holes trigger, circle holes trigger, and grooved aluminum tubes. The comparation result shows the thin-walled aluminum with circle holes trigger has highest mean crushing load(Pm), followed by oval holes trigger tubes, then the grooved aluminum tubes. |
