I'm having a try with the inventor simulation and i realized that it doens't use the real stress-strain curve of materials. By this being so, all the stress results pass largely beyond the ultimate strenght of materials. Is there a way of introduzing this curves in autodesk? There is softwares that have this ability, like Solidworks, so there must be a way in Inventor. Could please somebody tell me how to do it.
Solved! Go to Solution.
By design the Stress Analysis in Inventor is linear. If you need a non-linear analysis we recommend using Autodesk Mechanical Simulation. More info available here: http://usa.autodesk.com/adsk/servlet/item?siteID=1
There are other assumptions to the linear FEA used in Inventor, most of which are listed here: http://usa.autodesk.com/adsk/servlet/ps/dl/item?si
==== Copy / pasted here for your convenience=================================
Linear, static stress analysis assumptions are as follows:
If you have a problem where these assumptions are not valid, you can either upgrade to the full analysis software package or pass the problem on to an analyst who is equipped to deal with it.
