dc.description.abstractThis study explores the mechanism of deforming both bare metal tubes and composite-wrapped tubes by an expansion die under quasi-static loading as a form of energy absorbing device to enhance crashworthiness. Finite element analysis is presented in this study to validate the results of the experiment conducted in an accompanying study. Finite element models are created and analyzed based on the experimental parameters and conditions. Both two-dimensional and three-dimensional finite element models are used to compare with the results obtained from the experiment. Results from the two-dimensional model indicate a good agreement with the experimental data. Glass fibre-wrapped metal tubes also show increased steady-state reaction force as well as better specific energy absorption capacity for every layer of composite wrapped as compared to bare metal tubes. In addition, variations in experimental parameters such as the expansion die angle and frictional coefficient are also studied to explore the effect on the steady-state reaction force and the specific energy absorption capacity of the model. Possible optimization in the design of this model is also recommended for future studies.en_US
