Understanding fast macroscale fracture from microcrack post mortem patterns [PDF]
, 2011 Dynamic crack propagation drives catastrophic solid failures. In many amorphous brittle materials, sufficiently fast crack growth involves small-scale, high-frequency microcracking damage localized near the crack tip.

De-localizing brittle fracture [PDF]
Journal of the Mechanics and Physics of Solids, 2021 Extreme localization of damage in conventional brittle materials is the source of a host of undesirable effects. We show how artificially engineered metamaterials with all brittle constituents can be designed to ensure that every breakable sub-element fails independently.

Effects of High Toughness and Welding Residual Stress for Unstable Fracture Prevention
Applied Sciences, 2020 Unstable fractures generally occur in brittle materials under low-temperature service conditions. Toughness and welding residual stress are the main factors that should be evaluated when defining a brittle crack propagation path. In this study, a rainbow

Fracture mechanics of micro samples: Fundamental considerations
Materials & Design, 2018 In this review article we consider the crack growth resistance of micrometer and sub-micrometer sized samples from the fracture mechanics point of view. Standard fracture mechanics test procedures were developed for macro-scale samples, and reduction of ...

Investigation on the Applicability of Several Fracture Criteria to the Mixed Mode Brittle Fractures
Advances in Mechanical Engineering, 2013 Mixed mode brittle fractures are very common failure behavior for cracked brittle materials under loading, and therefore, the prediction of the mixed mode brittle fractures is significant.
