Urethane, 90 Duro strain energy

[chrisjk383]

Hey guys,

I need to know how much strain energy a rectangular piece of urethane has when compressed... For discussion purposes, say I have a 150mm x 200mm x 25thk block of 90 durometer urethane and I compress it 2.5m... How much force will this take? I've never calculated with Urethane before

Thanks

Strain is defined by the following webpage:

strain energy is the energy stored by a system undergoing deformation. When the load is removed, strain energy is:

That would work for me if I knew the modulus, does urethane have a set modulus "E"?

Yes... Figure out which particular Urethane you want and search up the specific Modulus of Elasticity.
