Fracture resistance of materials
1982This section will be concerned with the case of an existing crack; the conditions that led to the initiation of this crack are not of interest for the discussion. For a perfectly brittle extension of this crack by cleavage, the criterion for crack propagation seems fairly easy.

Evaluation of fracture resistance of ceramics: Edge fracture tests
Ceramics International, 2007Advanced oxide and nonoxide ceramics were tested by edge flaking with different indenters. Flaking toughness values obtained with the Rockwell indenter were shown to be practically proportional to fracture toughness values measured by the single edge V-notched beam (SEVNB) method.

Fracture Resistance of Nanocrystalline Ni
Metallurgical and Materials Transactions A, 2007Atomic level simulations are used to study crack propagation mechanisms in nanocrystalline Ni. Digital samples with a mean grain size of 5 and 8 nm containing 125 grains were used. For both grain sizes, the mechanism of crack propagation involves the formation of nanocracks along grain boundaries in the vicinity of the main crack.

Fracture Resistance of Aluminum Alloys
2019Abstract This article discusses the concepts underlying linear elastic fracture mechanics and elastic-plastic fracture mechanics as well as their importance in characterizing the fracture behavior of the high-strength aluminum alloys. It describes the three methods used for analyzing elastic-plastic fracture, namely R-curve concept, J ...

Fracture Resistant Titanium-Aluminum Laminate
1978In an exploratory program for the development of damage tolerant materials for aircraft and helicopter structures, it has been found that laminated panels composed of mill-annealed Ti-6A1-4V sheet and alclad 2024-T3 sheet provided unusual fatigue and fracture resistance.

Fracture Resistance in Multiphase Alloys
Key Engineering Materials, 2007The fracture behavior of Nb-based in-situ composites is reviewed to elucidate the effects of alloy additions on the fracture process in multiphase alloys. The overview paper summarizes the current understanding of the processes by which alloying addition and microstructure alter the near-tip deformation and fracture mechanism, and presents a ...
