Building a Submarine-Like Structure: Materials & Thickness for a Given Volume

In summary, there is no material that can passively maintain a constant volume under pressure. The only options are to design an active structural integrity system or determine an acceptable level of deformation. This applies even when dealing with 3-6atm of pressure. The conversation also mentions the use of a steel structure and the search for a formula to estimate wall thickness for a pressure of 6atm or 5atm. Additionally, the gas inside the structure is expected to be air at 1atm.

I´m trying to find approx. numbers or formulas for a submarine like structure to mantain a constant volume. For a given volume, which materials and to what thickness should the container be?

No material can [passively] maintain a constant volume under pressure. You'll have to either design an active structural integrity system or decide how much deformation is allowable.

Even when talking about 3-6atm´s? Understandable that everything has it´s limits. I´m looking at for example: a steal structure and trying to find a formula to estimate the wall thickness, considering there would be let´s say 6 atm´s of pressure or let´s say five to make the math easier. Thanks for your reply! Oh, and the gas inside would be air at 1atm.
 

1. What materials are commonly used to build a submarine-like structure?

Some common materials used to build a submarine-like structure include steel, aluminum, titanium, and composite materials such as carbon fiber reinforced plastic (CFRP).

2. How do the materials used in building a submarine-like structure affect its performance?

The materials used in building a submarine-like structure play a crucial role in its performance. Steel is known for its strength and durability, while aluminum is lighter and more corrosion-resistant. Titanium is often used for its high strength-to-weight ratio, and composite materials offer a combination of strength and lightness. The choice of materials will depend on the specific design and purpose of the structure.

3. How does the thickness of the materials used affect the structure's strength?

The thickness of materials used in a submarine-like structure can greatly impact its strength. Thicker materials can provide more structural support and withstand greater pressures, but they also add weight to the structure. It is important to strike a balance between thickness and weight to ensure optimal strength and performance.

4. What factors should be considered when determining the materials and thickness for a given volume?

Several factors should be considered when determining the materials and thickness for a given volume in a submarine-like structure. These include the depth the structure will be operating at, the type of environment it will be in (saltwater vs. freshwater), the expected pressure and stresses on the structure, and the desired performance and durability.

5. How can computer simulations be used to determine the best materials and thickness for a submarine-like structure?

Computer simulations, such as finite element analysis, can be used to model the performance of a submarine-like structure and determine the best materials and thickness for a given volume. These simulations can take into account various factors such as pressure, stress, and material properties to optimize the design and ensure the structure's safety and performance.
