Creo Parametric - Creo Simulate - Failure Index and Effective Communication

- This Creo Parametric / Creo Simulate tutorial video shows two different methods to communicate structural analysis results to your audience more effectively:
* Changing the legend in your results window to reflect the yield stress of your part's material.
* Modifying material properties to include a Failure Criterion and then generating Failure Index plots.

This is an awesome video. Thank you Dave !!!
Martin sir, you save my day, what a knowledgable video
Glad to hear it, Kamlesh!
This is the one video that is gonna make my career! I dont have words to express gratitude Dave..
Glad to hear that! Trust me, the lessons were hard-earned through a lot of frustration and embarrassment.
@@CADPLMGuy I can see how much effort has been put into your CAD management and Engineering journey.. wish I had a teacher like you in my Engineering classes! 💯💯
@@adhithasimhanraghavan7516 That's a great compliment. Thank you!
Thank you for sharing, its very useful
Glad it was helpful!
Is it possible to get the part file to work on it following your video ?
Hi there, I have a question, so actually after first analysis your results showed that the maximum stress is 610MPa and Ti alloy has a yield strength on a level of 880MPa. The conclusion was (obviously), that your part has a lot of spare strength and that it is going to withstand this force. Then, after second analysis where instead of stress your results showed failure index, same places (which previously where the places where the stress was on the level of 610MPa) had the value of failure index greater than 1. It means that they could (or even for sure are going to?) brake, am I correct? So basically, first analysis said that our part will be ok but second said that it will actually brake? I don't know whether I missed some details beetwen first and second analysis, maybe that's the reason. Could you please help me with this?
I did this video last August, and it was more than a hundred videos ago. I doubt I could remember what I was doing. Although I seem to recall adding some safety factor to the yield strength when I reconfigured the material properties.
I think he show us the second type of load in the index failure results ;) So more loads = more stresses
In the first run, he ran with the default settings for material selection. Then, he added 704 MPa and I probably think that is where some other variables have also changed slightly. May be he has shown study-1 the first time and study 2 results the second time. I am not sure about either of those.. just to add my guess..
Interesting, do you ever set the stress-strain response to anything but linear, or is linear usually good enough?
You use a non-linear stress-strain response when it's appropriate for the material, like a hyperelastic or elasto-plastic material, especially when you are simulating "push-through" (like you see with a kid's push pop fidget toy).
Sir, my doubt is I m getting 2200MPa in vonmises criterion. But the yield stress of steel is 260Mpa. Is this right ? Should I assume my material will be failed or should I think I have made some mistake? Will creo simulation show more stress than ultimate stress ?
Can we find factor of safety in creo?
Failure index is the inverse of factor of safety. Pls divide 1 by the max value you get in the failure index plot.
