[gmx-users] Rupture force definition

I have one query regarding pulling of si-rNA (having chain-a and chain-b).
Here, I am pulling 3' end of chain-a and fixed 3' end of chain-b
(diagonally apposite ). I am doing pulling using gromacs with constant
velocity rate using Umbrella sampling. after finalization of pulling before
umbrella sampling, we got two output file i.e.
1- force/time (f= force)
2- x/time (x= pulling distance between two ends)
in first case of f/t, initially force increases and then after some time,
to decrease (looks like gaussian curve, not exactly gaussian, because lot
of fluctuation). So my question is that, what this peak (of increasing and
decreasing curve ) represents. can I define this peak as a rupture force or
breaking force of two strands of si-rna or something else.
