Modelling and experimental testing of expanded granules as crash-absorber for double hull ships

In this contribution, expanded glass granules are investigated, which will be used to increase the crashworthiness in ship construction. Therefore, an experimental setup is presented. This setup represents a simplified side hull structure of a double hull ship. The empty space between the double hull structure can be filled with the granular material which acts as crash absorber.

The described experiment will be used to validate the finite element simulation of the penetration of the double hull with the bulbous bow. To model the granules the Mohr-Coulomb material model is taken advantage of. Based on the experimental data the suitability of the Mohr-Coulomb model will be discussed.
