Scaling transitions and size effects in the fracture and strength of materials and structures have particular significance in modern science and engineering, since the boundaries of mechanical phenomena studied and devices exploited are being pushed both out, towards global scale phenomena, and in, towards the nano-scale. These circumstances challenge the conventional wisdom acquired over many decades of laboratory experiments and modelling at the engineering scale (sub-mm to a few meters). More specifically, violations of the accepted scaling laws are observed, requiring new physical deformation mechanisms to be proposed or identified, and new modelling approaches to be developed and validated.
