STRUCTURAL IMPACT ON RETAINING CAGE
STRUCTURAL IMPACT ON RETAINING CAGE
(OP)
We have a pressure cap that is contained by a cage. If the cap blows off I've calculated the velocity at point of impact on the cage. I need to know if the resulting impact will make the cage fail. There are four posts holding the cage on.
I can calculate the resulting K.E. of the cap (.5*Mcap*Vcap^2).
I know the the charpy impact values of the post matl: 32 ft*lbs per 1in x 1in x iin test coupon.
if the volume of the posts is about 150in^3 and I know that 1in^3 of post matl could absorb 32 ft*lbs of K.E (per charpy testing), can I say the posts can absorb 4825 ft*lbs of K.E. (volume of post * charpy impacts)?
If I can say that then I could see if the K.E. of the cap projectile is less than the total energy absorption capacity of the posts. Let me know what you think.
Thanks for any advice!
