Abstract:
The purpose of this study is to investigate the effect of mesh sizes, plate thickness and
crushing force of a bulbous bow. The simulations only consider the lateral collision of
crushing plate between bulbous bows and the results is compared with available
experimental data. (Endo, Yamada et al. 2002) simplified experiments models are
used in this study and couple with FLO damage criteria to predict collapse mechanism
and rupture of bulbous bow. The simulation analyses also take into consideration of
speed of crushing plate that crush the bulbous bow. Throughout the analysis mild steel
S235JR material properties is adopted and coefficient of friction is set as 0.3 for
general contact friction of mild steel. The mesh sizes, plate thickness and speed of
crushing plate are set from (20mm-50tnm), (10mm - 25mm) and (0.6m/s - 5m/s)
respectively. The FLO damage criteria is discussed and the results gave a good
correlation between (Endo, Yamada et al. 2002) experimental data and finite element
analysis.
