Abstract: | Traditional materials are still widely used in ship manufacturing at present, but the development of newma-terials gradually brings in new inspirations of ship design and its performance optimizing recently. This paper aims to provide new strategies for vibration and sound reduction of ships from a material standpoint. Several kinds of popular new materials including new damping material, negative Poisson's ratio material, giant magnetostrictive material, functionally graded material, phononic crystal and phononic glass are introduced. Their working theories, current research progress worldwide and the prospects of application on vibration and sound reduction of ships are stated in detail. Hope this overview can be a reference to new materials' applications on the ship design in the near future. |
