Aerospace ILSS strength formula

  1. Aug 30, 2016 #1
    Hi all

    I'm trying to learn more about the tests i conduct at work.

    i do lots of short beam strength tests, we call them InterLaminar Shear Strength tests (ILSS).

    I have seen 2 different equations used to calculate strength.

    3 * fail load / 4 * width * thickness

    0.75 * fail load / width * thickness

    I feel quite comfortable rearranging these with simple algebra but was looking for a bit deeper understanding about how these were derived and especially why the coefficients are the values they are.

    Thanks in advance
