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 https://icme.hpc.msstate.edu/mediawiki/index.php/Uniaxial_Tension
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.
