Abstract

Research on energy absorption of metal has been conducted extensively over the years. Square, rectangular, circular, triangular and hexagonal shapes are the types of tubes that have been vastly investigated. The importance of this research is to measure and analyse the energy absorption characteristic of the manually fabricated tubes during impact. Axial crushing test is the most common experiment that is used to gain the energy absorption value. This report employed quasi-static axial crushing test. Square tubes, rectangular tubes, hexagonal tubes and triangular tubes were fabricated and joined by using zigzag MIG welding. From the experiment, it is found that hexagonal tube has the highest energy absorption value and triangular tubes had the lowest energy absorption value.
