Abstract

Conical structure is widely used in engineering industry such as automotive, oil and gas, aeronautical etc. Cone structure also saves the occupant of vehicles from axial collision by converting the kinetic energy of crash into another form of energy to minimize the impact of accident toward the occupants. This work presents a study on conical shell under axial crushing through experimental approach to identify the energy absorption capacity. Mild steel cone shell was fabricated with three different diameters that are 80 mm, 100 mm and 120 mm and all specimen height is 100 mm. The crosshead speed used in this experiment is 1 mm/min, 10 mm/min and 20 mm/min. The entire specimen will be tested under axial loading using INSTRON Universal Testing Machine. This experiment is to investigate the effect of crosshead speed and top diameter on energy absorption. It is found that the energy absorption will increase as the crosshead speed and diameter increase.
