Understandable. I really do appreciate all your help. I am apparently not in a good mood by not getting a definitive answer. Thank you all for your help. I believe its time to get my hands dirty again and just move on to prototypes. Thank you all!
Interesting thought there dhengr...let me think about it. I find it interesting that everyone is still under this amazing determination that this is about a steel or metallic product. Again, it isn't therefore a lot of the experiences that are being talked about above are useless. By the way...
IRstuff - That is correct. But in my case as I stated before I am only flexing this part a single time. There will not be a fatigue load in that direction. You are certainly correct though!
TVP - I have already reviewed a lot of these materials but no one speaks of the ability to "pull" the material back from yield on the outer surface by using a specified percent of unyielding material around the neutral axis.
DanStro - Yes, that is one of the ways that you determine the maximum...
Twoballcane - You must not be aware that compression springs can see 10x the ultimate strength on the outer surface and still meet over a million cycles.
ITstuff - The part I am currently dealing with is a simple plastic component that will flex around a snap feature and snap in behind it to...
But you can't simply consider the stress at the outer fiber. It is possible that the very outer fiber is the fiber that is in yield therefore you wouldn't ever notice it until you began to fatigue the material.
I understand the elastic limit or yield strength but when calculating a beam and determining if it will yield or not, this calculation can be figured throughout the thickness of the material. If a certain percentage of the material is not in yield the overall beam will not yield as the material...
Good Morning Everyone,
I am working on some beam deflection problems for work. I am calculating not just if the outer surface of the material is going to yield or not but exactly how deep the yield penetrates the material. Is there a standard practice percentage that yield can go into the...
