Kink/buckling homework

  1. Aug 3, 2014 #1

    I have a steel shaft which is loaded by a pressure force in axis direction.
    If I want to calculate the maximum force I have to proof if this is a kink according to Euler or not.

    For steel E295 there is a Lambda_p = 89

    In my case I calculated that Lambda is 125 --> Lk/i --> i = sqrt(I/A)

    Now my question is: What if Lambda is lower than Lambda_p?
    What do I have to do in this case?

    buell23: How is lambda_p computed?

    Thats an empiric value for diverse steel. For S235JR for example 104.

    But I looked for it in the internet. If Lambda < Lambda_p, we have to use way of Tetmajer.
