Abstract

Finite Element method was used to simulate the energy absorption for the circular ring in lateral compression. The simulation is base on the quasi-static lateral compression. The computer simulation was perfonned by Abaqus. The comparisons of experimental result and simulation results were done to verify the simulation result. The percentage error of energy absorbs between simulation and experimental result is around 21.58%. This is because the assumption in modeling (wire part) is the main source of error. However, it is found that the corresponding circular ring behaviors when onder lateral compression ring experiment are very similar to the theory. The thickness was neglected in computer simulation result the locking displacement of the compression was occurred early if compare to experimental locking displacement. Aluminium material has lower energy absorbstion capacity if compare with mild steel. This is because the mild steel has higher Young's modulus. This report was done and fulfills the title given in my Final Year Project.
