Re: [lammps-users] Problem in tensile test

you are now posting the *exact* *same* question to this list for the 3rd time within 24 hours.
what is the point for that?

if you do not get an answer immediately that can have one or more of the following reasons:

- nobody knows the answer
- nobody cares
- people that could help you are busy
- people think that you should figure out the answer yourself for maximum learning effect
- people don't understand what you are asking

​the general rule of the thumb is to wait at least 48 hours (or correspondingly more, if there is a weekend in between) before reposting,
and then you should also consider making your question more compelling, providing more explanations, details, thoughts, on the problem at hand.

just repeating the same question over and over again will only get you responses like this one.

Hi all,
I was just trying to do some uniaxial tension test by using fix_deform and as a specimen sample I took single crystal Al. I use the available lamps script at

But, surprisingly I do not see any fracture even after the strain value of over 200%. The sample is stretched unusually at that high strain. I have seen a recent post about this type of behaviour but do not see any comments over it.

Could anybody please make some suggestion what I'm missing.

Thanks for your help in advance.
