Modern submarines rely on their hull design and material construction to deal with extreme pressures in the ocean while submerged. Most NATO countries use a flexible, compressible steel alloy that allows the hull to compress and expand as the submarine goes deep and shallow. The decks aren't actually connected to the hull - if they were, they'd be severely damaged as the boat goes deep. They're actually suspended by cables, the sides of the decks several inches from either side of the hull to prevent contact.
Not all submarines use this type of construction, and it can be a problem later down the road in the life of the boat. For example, the Russians have used Titanium to construct some of their boats. While strong and allowing them to go deeper, Titanium isn't flexible, and over time under repeated pressures it will become brittle. Others like China use GRP (fiberglass) to construct their boats. The problem with having non-flexible material is the egg-shell effect - egg shells are strong, but under enough repeated pressure they become brittle because they cannot compress and expand.
A spherical based design is also the strongest for extreme pressures, and why virtually all modern submarines are based on a cigar or teardrop shaped hull design.
What else can I help you with?
Why submarines are built with hard thick sheets of metal?
To withstand the external pressure.
Why cannot submarines go in deepest parts in oceans?
As submarines go deeper they are surrounded by more and more pressure from the water arround them. There are not currently any submarines that can withstand that amount of water pressure.
How does pressure affect submarines?
Pressure significantly affects submarines as they operate in deep ocean environments where water pressure increases with depth. As a submarine descends, the external pressure can compress the hull, requiring it to be designed with strong, reinforced materials to withstand these forces. If the pressure exceeds the structural limits of the submarine, it can lead to catastrophic failure. Submarines also use ballast systems to manage buoyancy and counteract the pressure effects during dives and ascents.
Why are submarines built of hard thick sheets of metal?
To withstand high water pressure when they are submerged at sea.
Why are submarines strong?
because they have to withstand the pressure of the water when they go down under water. and to keep the people safe :)
Do army submarines have windows?
No, military submarines do not have windows like those found in surface vessels. Instead, they use thick, reinforced steel hulls to withstand high pressure underwater. Any necessary visual observation is typically done through periscopes or cameras, which are designed to maintain the submarine's stealth and structural integrity.
Why submarines are made of thick sheet of metal?
As a submarine submerges, it is subjected to a high volume of water pressure, which increases the further in depth the submarine goes. They have to be built to be able to withstand this pressure.
What is use of pressure vessel in submarine?
Pressure vessels in submarines are crucial for maintaining a stable internal environment despite the high external pressures of deep water. They house equipment and living quarters, ensuring crew safety and comfort by preventing water ingress. Additionally, these vessels are designed to withstand significant pressure differentials, allowing submarines to dive and operate at great depths without structural failure. Their integrity is vital for the overall performance and survivability of the submarine.
Why does submarines have water resistance?
Submarines are designed to be water-resistant to withstand the immense pressure of the ocean at various depths. This water resistance is achieved through a robust hull construction, typically made of high-strength steel or titanium, which prevents water from entering the vessel. Additionally, submarines utilize specialized seals and systems to manage buoyancy and ensure that they remain watertight, enabling them to operate safely and effectively underwater.
How a submarine does not crush under water?
Submarines are designed to withstand the immense pressure of deep water through their strong, streamlined hulls made from high-strength materials like steel or titanium. Their shape allows them to distribute pressure evenly across the surface, preventing weak points. Additionally, submarines are engineered with internal structures that provide further support and integrity, ensuring they can operate safely at various depths without being crushed.
How can submarines with stand pressure?
Submarines withstand pressure through their robust hull design, which is typically made from strong materials like high-strength steel or titanium. The hull is shaped to distribute external pressure evenly, minimizing stress concentrations. Additionally, submarines are built with a double-hulled structure or reinforced sections to enhance structural integrity. Advanced engineering and thorough testing ensure that they can safely operate at great depths.
Why do submarines have to be strong?
Submarines would need thick, strong walls because They would have to withstand the pressure of the water that would increase the deeper they go, to do this they would need stronger and thicker materials to cope with the force (This would help keep the people safe).
