    Young's Modulus and elastomers


    I was wondering if Young's modulus is the same as 100% modulus in the rubber world.

    Also, can I use the 100% modulus value to calculate the force required to compress a rubber by a certain amount, say 20%.

    Thank in advance.

    I believe "100% modulus" is in reference elongation at 100%. Since Young's Modulus is variable - depending on the amount of elongation the modulus maybe given dependent on applied elongation.

    For an elastomer material - use whatever the engineering specifications provide for the Young's modulus...
    Tell me and I forget. Teach me and I remember. Involve me and I learn.
