Quenched disorder and instability control dynamic fracture in three dimensions

Facet formation in slow three-dimensional fracture

Understanding the fracture toughness of glasses is of prime importance for

science and technology. We study it here using extensive atomistic simulations in

which the interaction potential, glass transition cooling rate, and loading geometry

are systematically varied, mimicking a broad range of experimentally accessible

properties. Glasses’ non-equilibrium mechanical disorder is quantified through

Ag, the dimensionless prefactor of the universal spectrum of non-phononic
