Could you tell me know which criteria if satisfied, the abaqus give this error "one of your elements distorted excessively"?

Submitted by Dincoz on

For test reasons of abaqus work, I have defined my material properties (stress-strain behaviour) up to strains of 15! However, even in this condition some of my elements reaches this strain value and distorted. I want to know which calculation the abaqus software is using to report a distortion error? 

Actually can we define our material behaviour in a way that, it would not distorted at all?

Friends of Extreme Mechanics Letters

When I traveled in China in June, I was once again irritated by the Internet.  It was often slow and broken.  Many important services are inaccessible, blocked by someone.  Why would someone do that?

But I found my Chinese colleagues extremely well interconnected.  Everyone has a cell phone.  They actually use their cell phones!
