In this paper, we present an athermal mechanical investigation of a two‐dimensional silica glass. We generate the network artificially using a Monte Carlo bond switch algorithm and compare our network with experimental results. Using an athermal quasistatic mechanical deformation method, we show that the two‐dimensional network glass reveals ductile fracture behavior, whereas the crystalline polymorph behaves purely brittle.
