A review of experimental approaches to fracture toughness evaluation at the micro-scale

The discipline of fracture mechanics was born almost a century ago through the pioneering work of A.A. Griffith, and saw particularly rapid growth in the second half of 20th century when it became an indispensable tool in the development of advanced transportation, civil construction, and energy systems. Forty years ago, Materials & Design published a series of papers devoted to the state-of-the-art in the field of Fracture Mechanics. The...
