Impact resistance performance of ship plates

TAGS: impact | plates | ship |

Ship plates are a crucial component in shipbuilding as they form the structural framework of the vessel. They are subjected to numerous stresses and environmental factors, including impact forces. Therefore, the impact resistance performance of ship plates is a critical consideration in ship design.

Traditional ship plates were made of mild steel, which has lower impact resistance compared to other types of steel. The high-stress areas of a ship, such as the bottom and sides, require higher grades of steel to withstand impact forces. Therefore, shipbuilders now use thicker and stronger steel plates for critical parts of a ship.

The most commonly used high-strength steel for shipbuilding is EH36, which has excellent impact resistance performance. This type of steel is also known as marine-grade steel, and it is specifically designed to withstand harsh marine environments.

Impact testing is used to determine the impact resistance performance of ship plates. One common test method is the Charpy impact test, which involves striking a notched sample with a heavy pendulum hammer. The amount of energy absorbed by the sample during the impact is measured, and this value is used to determine the material's impact resistance.

In addition to selecting the right type of steel, shipbuilders can also improve the impact resistance performance of ship plates by altering their shape and design. For example, curved shape plates offer better impact resistance than flat plates as they distribute the force of the impact more evenly.

the impact resistance performance of ship plates is a crucial consideration in shipbuilding. Shipbuilders need to select the appropriate type of steel based on the specific needs of the vessel and subject the plates to rigorous testing to ensure they meet the required standards.
