I am faced with a little problem. I have a pyramid (or another shape) in foam. I know its impact compression (stress-strain curve) and as a consequence the energy it can absorb.
Now, the problem:
I want to absorb a certain amount of energy with a pyramid of foam.
What is the size of the pyramid I can use? How can I easily use the characteristics of the first pyramid for the new one?
Let me know what is your point of view.
