dc.description.abstractPerforation due to the falling of foreign bodies on the offshore structures is one of the key concerns in the field of structural design. These structural damages may be fatal and decrease the integrity of the overall structure. This provides the motivation for researchers to analyze and develop guidelines in this field. In this dissertation, a numerical model of a low velocity foreign body impacting on a stiffened plate is created. The numerical simulations of this model have been performed using ABAQUS/CAE-Explicit. The numerical model is created in accordance with the experimental set-up reported by Langseth and Larsen[ I]. The results of the simulation are validated via comparison with the results of the published experimental data. Good agreement was found between the numerical model and experiment. The maximum velocity at which the plate does not undergo perforation and the minimum velocity at which the plate is ·perforated was also found. The stiffened plate is analyzed using different support condition to look at the effect of boundary conditions. Few structural design suggestions with stiffeners are proposed to resist against the plugging of plates for the future study in this area of research.en_US
