Impact and material strength 1

[PGasT]

I am doing a project in which a safety containment structure needs to be designed. Specifically, I need to design a structure that will house a turbocharger in case of a blade burst. I have the energy of the blades, and need to find how much energy will be lost going through the housing (cast iron). What is the best way to approach this problem based on the blades impacting the housing with very high energies? Additional containment will be used, but the energy of the projectile leaving the housing is needed before design can progress.

Here is a start.

Use the same concept for an outer barrier.

There are some good equations in that paper. I was looking through it though, and it is really vague on what units to use since they seem like empirical equations. I tried looking up some of the equations, and couldn't find too much on them either.

On turbine secondary containment people assume that the primary failed and that you have to contain blades at full force.
They like using stainless steels because you can get fairly high strengths, excellent toughness, and very high strain hardening rates.
This application is somewhat related to blast protection for armored vehicles. At lest the theory and some of the material selection criteria are similar.
