Fracture has been a grave concern for practical applications of graphene and other atomically thin and brittle materials. By contrast, in this issue of Matter, Ming et al. present a method to harness the power of fracture in controlled fabrication of …
The interaction between cracks and inclusions plays an important role in the fracture behavior of particulate composites. It is commonly recognized that an inclusion stiffer than the matrix tends to deflect an approaching crack away while a softer …
Carbon micro/nanolattice materials, defined as three-dimensional (3D) architected metamaterials made of micro/nanoscale carbon constituents, have demonstrated exceptional mechanical properties, including ultrahigh specific strength, stiffness, and …
The past century has witnessed the development of fracture mechanics as both a field of fundamental science and an active engineering discipline with ever increasing applications that involve structural failure and reliability. This lecture is aimed …
Topological defects (eg, pentagons, heptagons, and pentagon–heptagon pairs) have been widely observed in large-scale graphene and have been recognized to play important roles in tailoring the mechanical and physical properties of two-dimensional (2D) …
A key challenge in large-scale graphene fabrication and application is controlling the grain boundaries (GBs) in polycrystalline graphene grown by chemical vapor deposition (CVD). Here, we adopt a phase field crystal (PFC) model to predict the …
Perfect graphene is believed to be one of the strongest materials, yet its resistance to fracture is much less impressive. The modest fracture toughness is thought to be related to the general brittle nature in the fracture process of graphene and …
