Hi all.
I am conducting some low velocity drop test experiments. The test specimen is clamped and held inside a cradle which itself is attached to a load cell. The load cell works in tension and records the force on the cradle.
I believe that the KE just before impact is dispersed in three main ways:
-Absorbed by the specimen by plastic defomation
-On the clamp that holds the specimen - this force is read by the load cell
-The residual velocity of the projectile (if any)
Plus noise and other small losses.
So, my question is, how can i get an energy value from the load cell reading? I need this to find the energy absorbed by the specimen. The load cell gives me a force v time graph. I believe the area under this curve is the impulse, but I'm unsure how I can equate this to an energy value.
Any help would be great - Thanks a lot.
Cheers
