      Hi guys,


      How to apply or set Factor of safety to our problem.I dont want to find the Factor of safety, I want to apply it to a problem and get my analysis done.

      Factor of safety is not an input, it is an output of the model.


      You have to solve the model once, get the Factor of safety, then scale something in the model to achieve the desired Factor of safety.

      Hello Peter ,


      I already did a factor of safety analysis and got a value above 1 (and 1.5).


      But I have been given a task to do a structural analysis considering a factor of safety of 1.5 .


      What should I do in this case.

      If your minimum factor of safety is above 1.5 you are done.


      Exception is if you have to optimize the structure and you are required to reduce the mass of the structure until you get to exactly a factor of safety of 1.5, then you have more work to do.
