Element deletion

[flyforever85]

I'm trying to understand how the ductile damage works and I built a simple notched sample, Steel 304, I added elastic and plastic properties and ductile damage values following one of the tutorial online. The sample is fixed on the left end and on the right end there is a velocity of 400 mm/s. Time on analysis is 0.1 sec, of course Dynamic Explicit. I also set Element Deletion YES in the mesh properties. Why I get these distortions? (see pic)

[FEA way]

Do you have the STATUS variable requested for output and selected in Result —> Field Output —> Status Variable --> Use status variable ?

I did not. But I'm re-running the analysis and I requested this variable. What kid of info should I get form it?

EDIT: just check the manual, interesting. I'll let you know what's the answer

 

[FEA way]

This variable is necessary to remove deleted elements from visualization. It can be also used to see which elements failed.
