Hello all. I am working on a assignment in which I have to determine if a projectile travelling at a known velocity will break through a side of its containment room (assuming worst case senerios). I have been looking online and in my textbooks and have ended up confusing myself on what equations I need to use. I have looked at stress equations, THOR equations and piercing equations. Can any one please point me in the right direction on what the best way of modelling this problem would be and the best equations to use. For information purposes if it makes a difference, the projectile is going to be travelling at a maximum velocity of 84m/s and weights 1kg and the containment room is made out of mild steel currently 1.2mm thick. Thank you for any help.
