Hello, I have a non-linear static analysis model which includes brackets assembled by spot weld( I defined bonded contact from circular faces to simulate that). The thing is I got very wildly different results when I checked the von misses stress with varying options of display (Such as elemental mean and averaged) and different positions( Such as top\/bottom and mid plane). I checked manual and did some research online but I confused and could not be sure about how to evaluate this solutions, I am trying to check that part is beyond the yield or how far beyond the yield but I can not be sure.<\/p>\n

for example this is midplane- averaged ;<\/p>\n

<\/p>\n

And this is mid plane elemental mean<\/p>\n

<\/p>\n

And this is the top\/bottom average<\/p>\n

<\/p>\n

I have to decide about this part going beyond the yield or not and for bottom\/top surface its beyond the yield and for mid plane it is not beyond the yield. I usually expect to see lower stress values in mid plane so that’s why I was always deciding this kind of situations by check results in averaged, top\/bottom surface. But I saw higher higher stress values in mid-plane for different force values than the screenshots I shared, the parts are not thick they re about to 1.5-3 mm thickness. How should I decide how to I check? Also I know how elemental mean and average display options works but I was not expecting see this much different results, is it better to check parts from elemental mean to ignore false stress which happens in 1-2 node? I am really lost, please help and I will be glad if you could advise me some training pdf, video or book about this topic to learn it deeply and make %100 sure about it.<\/p>\n
