AbstractA finite element model of graphene strip is developed to predict the instability of dynamic fracture, in which the C-C bonds are represented by Timoshenko beam elements, and the constitutive relation of beam is derived from the atomic potential. Crack instability and branching are observed under loading strain rates from similar to 10(-5) fs(-1) to similar to 10(-8) fs(-1). Under low loading rates, the initiated midway crack propagates straight at supersonic velocity, while kinking and oscillation occur beyond a critical crack velocity similar to 10.33 km/s under high rates. The results demonstrate that our equivalent models could provide efficient information for studying the fracture in graphene. (C) 2015 Elsevier Ltd. All rights reserved.
