Elastomer Energy Return
Hello,
I'm developing a product which requires a shock absorbing elastomer to compress slightly during an impact, then rebound providing energy return, similar to how some running shoes give a spring like effect.
I'm just trying to clarify, does the rebound / energy return occur when
[LIST][*]The force causing the compression is removed, or[*]It is related to the natural frequency of the material. I.e. the energy return occurs after a period of time in accordance with the frequency of the elastomer.[/LIST]
I'm finding conflicting information so I'm just looking for clarity.
Thanks in advance

Energy return = (Energy in) - (Energy absorbed).
You need to estimate the Transmissibilty of the elastomer, then Natural Frequency and compare to application. This will give you an idea on the return energy.
