Re: Difference between element and Nodal element stress

HI Ionut,

 

I think that I uderstand your point now, however still assumption that crack appeard for stress less than yield, for me is just wrong unless it is not a fatigue case byt clear overloading of the strructure. But it's just my opinion.

 

What I can suggest try to use element CRAC3D, described Here.

 

I have never used it, but it seems to be answer for your problem with modeling of tiny notches.

 

As I can see it is suported by NX Nastran Basic Bundle.

Let me know if you will ger reasonable results Smiley Happy

Hi,

Yes, it is a fatigue case. I will have a look at the element you mentioned, and I will keep you informed.

Many thanks
