After all a “von Mises contour plot” must be the most checked thing when it comes to FEA outcomes!Īnd there is a good reason for that! After all, stress is the best measure of how much “hurt” your model took with all the load you applied! I think this is a step most people instinctively use. I guess this will come down to personal preference! To be honest you can perform those steps in a different order and still be fine. I number the steps simply to give you a certain framework you can use later. It is just a stress contour plot!Īll right then, let’s check how to approach FEA outcomes step by step! How to interpret FEA results: Step #1 Just note: apart from the fact that the above graphic looks pretty cool, it has little to do with “FEA outcomes”. This means that you can in the very least display something like that: Simple as that! But here I will assume that you’ve nailed boundary conditions, loading, meshing, and analysis setup. Proper interpretation of wrong outcomes lead to wrong answers! Even if you analyze outcomes properly, if the model itself was wrong this all thing can end pretty badly! Firstly, let’s assume you have a correct model – without that, we won’t get far. This is such a broad topic, that I feel we need to set some boundaries on it. Learn even more about interpreting outcomes!.Common errors in FEA results interpretation.This is a long post (solid 30 min to read it all!), so I’ve made a content list. To help you out on your way I figured I will share the most important things from my experience with you! I’m constantly learning how to interpret outcomes better, even after 10 years in the practical FE design field. This all may sound simple, but of course, there are many nuances involved. Of course, there may be other checks depending on what analysis you are doing (like fatigue, vibrations, etc.). Don’t forget to verify if model deformations are sufficiently small. Verify if you have stability issues (i.e. If your model yields, check if plastic strains are acceptable. Firstly, verify if yielding is not present (or acceptable). In structural design, you have to perform several checks. Let’s take a closer look at how to approach this task! Firstly let’s wonder how to interpret FEA results? Even if you already have proper values from your FEA analysis, still you need to decide how to interpret FEA results. Interpreting analysis outcomes is not simple.
