Griffith criterion for brittle fracture in graphene.
There are prevailing concerns with the critical dimensions when conventional theories break down. Here we find that the Griffith criterion remains valid for cracks down to 10 nm but overestimates the strength of shorter cracks. We observe the preferred crack extension along the zigzag edge in graphene, and explain this phenomenon by local strength-based failure rather than energy-based Griffith...

متن کاملFracture in Disordered Brittle Media
This thesis consists of three main chapters, an introduction, and an appendix. The introduction (chapter 1) gives a general historical introduction to the problem of brittle fracture in disordered media. Chapters 2 and 4 are concerned with various aspects of fracture in disordered fuse networks. Chapter 2 investigates the asymptotic properties of fracture strength distributions, and explores th...
متن کاملPeridynamic models for dynamic brittle fracture
Adviser: Florin Bobaru Damage and failure in composite materials under dynamic loading has been extensively studied in experiments for several decades. Composite materials exhibit various damage and failure patterns under different loading rates, such as splitting and branching. Classical models cannot directly be applied to problems with discontinuous fields. A new nonlocal continuum model, pe...
متن کاملFractal Dimension of Brittle Fracture
Using a worldwide catalog of earthquakes we analyze the distribution of distances between pairs of earthquake hypocenters to determine the spatial fractal dimension 6 of an earthquake fracture. As the time span of the catalog increases, 8 asymptotically reaches the value 2.1-2.2 for shallow earthquakes. Approximately the same asymptotic value of dimension is obtained for a catalog of earthquake...
