Impact Stress on Bracket

  1. Feb 14, 2011 #1
    Hi all,

    I am trying to calculate a value for stress in a right angled bracket. this would be simple for me if the load was a static load, it would cause the bracket to bend around a point etc so i can get moments to find its bending stress.

    however this bracket will be stopping a moving cart, to act as a mechanical stop.

    The cart travels towards the bracket, it has a mass and an acceleration. on impact, how can the stress in the bracket be derived.

    on first thoughts, i would try Castigliano's method for strain energy. Am i right in thinking this?

    any pointers on what methods to look into would be great.
