Experimental testing and numerical simulation of granules as crash absorber for double hull structures
Zusammenfassung
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.
