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.
