Real versus actual measurments?

I am new to SimSolid.  It seems very capable and has a lot of features I have not explored.  But I have one area of concern, how does it relate to real world experience.  Below is simple pipe:

  • 47” long
  • wall thickness of .065”
  • Material is as below, Chromoly steel.  Note that I get very similar results with AISI 4140 steel - Normalized from the default database

  • Immovable at each end of the pipe (the faces)
  • Load in the center  on a .25” diameter circle is 50 lbs

As you can see the calculated displacement is .044727” in the center.  Yet, if I take a piece of real chromoly pipe and load it like this its displacement is 0.165” in the lab,  a 4X difference.  Either the tool isn’t good at thin wall tubular material, or I am doing something wrong.  Given all that I have read about the product, tutorials, etc. I am inclined to think the issue is how I am using the tool.  But this is pretty simple analysis given the vast capabilities of the tool.   Thoughts?

    Hello Rick,

    I noticed that you performed the analysis on SimSolid version 22.2, which is much older than the current 24.1 version. A lot has improved including thin solids handling. I would suggest you to try the latest version and see the comparison. If you can share the ssp file with me to see the setup and try on my end.

    Regards,
