[lammps-users] problem with lower strain rate

Dear All

I am doing a tensile test on copper wire (13 x 0.72 x 0.72 nm) at 10K.
no periodic boundaries are used.

when i apply a strain rate of 10^10/sec along the length, wire gets fractured after sometime.
but when i apply strain rate of 10^9/sec, wire extends up to a strain of 0.08 and it remains at fixed length with out getting fractured even after running long time.

Any one can help me


Through viz, you need to figure out why the system stops straining. Something
must change at a later time.
