Has anybody been able to confirm the accuracy or inaccuracy of Inventor stress analysis results?
I couldn't confirm the physical properties that Inventor has of aluminum itself because I checked many websites for some of the properties and they disagreed on some of the properties, so I can't tell if Inventor has bad data, if Inventor makes the calculations incorrectly, or if I'm hugely overestimating the strength of aluminum.

Keep in mind that programs like COSMOS or Inventor deform the model as a graphical representation of the colored data they'll typically place onto the model. The deformation you see on the screen is exaggerated to make it easier to detect.
