Test and numerical analysis on the damage characteristics of double-hull ship structures suffering head-on collision by a wedge indenter
<b>[Objectives]</b> The result of ship collision is often catastrophic,especially a marine ecological disaster caused by the collision or stranding of double-hull oil tanker is difficult to recover from for many years. In order to assess the crashworthiness of double-hull structure,the t...
