A study on auxetic-inspired side structure for enhanced crashworthiness
https://orcid.org/0000-0002-7661-5269
Abstract A novel type of side structure of ship is proposed, inspired by auxetic materials with a negative Poisson's ratio, for enhancing the crashworthiness of double-hull vessels. Three different unit cells (VRE, HRE, and ARR) are designed and numerical simulation is conducted to demonstrate their resistance to collision. A comparative study on the crashworthiness of the proposed side structures and those of traditional side structures (double hull, X-core, and Y-core) is performed and a superior capability of energy absorption and collision resistance of the proposed side structures is observed. These findings demonstrated a potential for auxetic-based structures to be applied as a collision resistance structure implemented in various protective structures.
Highlights A novel type of side structure of ship inspired by auxetic material is proposed. Enhanced crashworthiness is achieved by the proposed side structures. The capability of energy absorption per unit mass of the proposed side structures is better than those of the conventional side structures. The crashworthiness of the proposed side structures could be further improved by replacing the material of internal structure from steel to other lightweight material.
