Study on Bending Characteristics of Square Tube Using Energy Absorption Part

Authors: Shigeyuki Haruyama, Ken Kaminishi, Zefry Darmawan

Abstract:

In the square tube subjected to the bending load, the rigidity of the entire square tube is reduced when a collapse occurs due to local stress concentration. Therefore, in this research, the influence of bending load on the square tube with attached energy absorbing part was examined and reported. The analysis was conducted by using Finite Element Method (FEM) to produced bending deflection and buckling points. Energy absorption was compared from rigidity of attached part and square tube body. Buckling point was influenced by the rigidity of attached part and the thickness rate of square tube.

Keywords: Finite Element Analysis, Rigidity, Energy Absorption, bending stress, square tube
