    S-N curve in SOLIDWORKS Simulation

    Rudolf Van den Berg

      Good day

       

      I have a Question that needs some clarification please.

      Correct me if I am wrong but it seems that for most materials there isn't a S-N curve defined to it.

      I know that if you go into your material database some of the materials has (ss) next to them which is the stress strain curve, and then only a few has (SN) next to the material, which is the S-N curve.

       

      Now my question is, why aren't the SN and SS curves assigned to all the materials?

      It seems to me that, if for instance you need the S-N curve for Alloy steel that you must manually punch in the values and create the S-N curve.

       

      There is also no (SN) next to any Steel materials in your database.

      I know you also have a database for a few S-N curves as soon as you create a fatigue study. but this is also limited to only a few materials.

      Any advice or feedback would be much appreciated.

       

      Kind regards
