The relationship between the moment and curvature

  1. May 17, 2012 #1
    I want to know why the moment could be represented as the product of the bending stiffness and the curvature. I do not quite understand the function of the curvature in the formula.

    Because high curvature means you deformed the material more, which means you are applying a large moment. See Euler's beam formulas

    Sorry that I did not make it clear. I want to know the steps of the derivation for the correlation between the curvature and bending stiffness.
