Hi PhysicsForums, first post!
So I was wondering how much energy would be absorbed by a shock absorbing material before it hit a vulnerable object. I've made a rudimentary sketch in paint to illustrate the situation.
I've calculated the Kinetic energy of the incoming object (let's call it X) and I want to know how much of that would go through to the fragile object (Let's call it Y). I know all the technical properties (tensile strength, thickness, density, all that good stuff) of the absorbing material and I've calculated the dynamic deflection/deformation that it would undergo when hit by X kinetic energy, but I'm just not sure how I would go about finding how much of that X kinetic energy would be absorbed by Y.
Any relevant formulas and methods would be greatly appreciated. For example, I know that thickness plays a part in how much energy is absorbed, and so does the deflection...but the formulas and how I would calculate how much of X is transferred to Y I'm clueless about.
P.S. the shock absorbing material and the object Y are connected via some sort of glue...I don't know if that makes a difference.
Thanks again!
