In the maritime sector, the collision safety is an essential aspect of ship operation. Aiming at further improvements,thefillingofthecavityinadoublehullstructurewithgranularmaterialisinvestigatedinthis thesis. Inordertodoso,thepotentialofdifferentgranulesisdeterminedexperimentally,alongwiththedescription of their material parameters as particles and as a bulk material, respectively. Furthermore, a simplifiedsidehullstructureisdesignedforexperimentaltesting,followedbyanumericalstudyofdifferentmaterial models for the granules. This leads to the simulation of a realistic collision scenario, showing the potential in the maritime industry.
