Pressure test containment wall thickness

In summary, the conversation discussed the calculation of minimum thickness for a containment sheet steel wall based on the velocity, mass, and diameter of a missile from a failed pressure test. The question was compared to designing military armor and the need for both ductility and areal density at different velocities. A recommended reference for further information on the topic was also mentioned.

Hi
If I know the velocity, mass and diameter of a missile from a failed pressure test how can I calculate the minimum thickness of a containment sheet steel wall say 1 meter away?

That is not a simple question. Many parameters would come into play.

Your question IMO is the same as that of designers of military armor. Think battleships and tanks. Research armor design. Maybe some other PF member can recommend a textbook on armor design.

At low velocity, less than about 100 to 200 feet/second, you need ductility and edge support to stop the momentum. At high velocity, over about 500 feet/second, you need areal density to stop the kinetic energy. In between, you need both.

A good reference is Structural Failure by Wierzbicki and Jones. It is a good source, but has more detail than you really want.
 

What is a pressure test containment wall?

A pressure test containment wall is a structure designed to contain and withstand high levels of pressure, typically used in industries such as oil and gas, chemical, and nuclear power.

Why is the thickness of a pressure test containment wall important?

The thickness of a pressure test containment wall is important because it directly affects its ability to withstand and contain high levels of pressure. A thicker wall can withstand higher pressure levels compared to a thinner wall.

What factors determine the thickness of a pressure test containment wall?

The factors that determine the thickness of a pressure test containment wall include the type and magnitude of pressure being contained, the material used for the wall, and the design and construction standards set by regulatory agencies.

How is the thickness of a pressure test containment wall determined?

The thickness of a pressure test containment wall is determined through engineering calculations and simulations, taking into account the factors mentioned above. These calculations consider safety factors and ensure the wall can withstand the expected pressure levels.

What are the consequences of an inadequate pressure test containment wall thickness?

An inadequate pressure test containment wall thickness can result in wall failure, causing a release of pressure and potentially hazardous materials. This can lead to environmental damage, injuries, and even fatalities. It can also result in costly repairs and damage to equipment.
