  We revisit a simple dynamical model of rupture in random media with
long-range elasticity to test whether rupture can be seen as a first-order or a
critical transition. We find a clear scaling of the macroscopic modulus as a
function of time-to-rupture and of the amplitude of the disorder, which allows
us to collapse neatly the numerical simulations over more than five decades in
time and more than one decade in disorder amplitude onto a single master curve.
We thus conclude that, at least in this model, dynamical rupture in systems
with long-range elasticity is a genuine critical phenomenon occurring as soon
as the disorder is non-vanishing.
