Brittle‐ductile coupling: Role of ductile viscosity on brittle fracturing [PDF]
Geophysical Research Letters, 2005 Localized or distributed deformations in continental lithosphere are supposed to be triggered by rheological contrasts, and particularly by brittle‐ductile coupling. A plane‐strain 2D finite‐element model is used to investigate the mechanical role of a ductile layer in defining the transition from localized to distributed fracturing in a brittle layer.

Ductile steel fibre composites with brittle and ductile matrices [PDF]
Composites Part A: Applied Science and Manufacturing, 2014 Abstract Due to the intrinsic brittleness of high performance fibres, traditional structural fibre-reinforced composites have limited ductility and toughness. In the present work a new class of fibres is explored for the reinforcement of polymers: continuous stainless steel fibres that simultaneously possess a high stiffness and a high strain-to ...

From brittle to ductile: a structure dependent ductility of diamond nanothread
Nanoscale, 2016 As a potential building block for the next generation of devices or multifunctional materials that are spreading almost every technology sector, one-dimensional (1D) carbon nanomaterial has received intensive research interests. Recently, a new ultra-thin diamond nanothread (DNT) has joined this palette, which is a 1D structure with poly-benzene ...
