| Summary: | . Many researches has been done on the lateral collapse of tube. However, the previous researches
only focus on cylindrical and square tubes. Then a research has been done discovering the collapse
behaviour of hexagonal tube and the mathematic model of the deformation behaviour had been developed
[8]. The purpose of this research is to study the lateral collapse behaviour of symmetric octagonal tubes and
hence to develop a mathematical model of the collapse behaviour of these tubes. For that, a predictive
mathematical model was developed and a finite element analysis procedure was conducted for the lateral
collapse behaviour of symmetric octagonal tubes. Lastly, the mathematical model was verified by using the
finite element analysis simulation results. It was discovered that these tubes performed different
deformation behaviour than the cylindrical tube. Symmetric octagonal tubes perform 2 phases of elastic -
plastic deformation behaviour patterns. The mathematical model had managed to show the fundamental of
the deformation behaviour of octagonal tubes. However, further studies need to be conducted in order to
further improve on the proposed mathematical model |
