Fracture of Brittle Microbeams
Journal of Applied Mechanics, 2004The random polycrystalline microstructure of microbeams necessitates a reexamination of the crack driving force G stemming from the Griffith fracture criterion. It is found that, in the case of dead-load conditions, G computed by straightforward averaging of the spatially random elastic modulus E is lower than that obtained by correct ensemble ...

Two classes of fracture are defined: I — fracture path completely predictable, and II — fracture path predictable only after initial random propagation. Class I fractures occur when there is a line of principal stress passing through the tip of the initiating notch or slit across which the stress is a maximum away from the tip.

Mechanistic Aspects of Fracture I ~ Brittle Fracture Models
2016Brittle fracture models proposed as the mechanism of hydrogen embrittlement are presented. Basic notions on the crack instability and its criteria are explained. Hydrogen effects are included in parameters used in the criteria. Involvement of plasticity is crucial even for apparently brittle-like cases, and various expressions for effects of plasticity

Most rocks specimens fail violently and uncontrollably at their peak strength when tested under unconfined stress conditions in conventional hydraulic loading systems. At failure their resitance to carry load rapidly drops to zero. This behaviour is commonly known as the “brittle” behaviour of rocks.

This is an advanced text for higher degree materials science students and researchers concerned with the strength of highly brittle covalent–ionic solids, principally ceramics. It is a reconstructed and greatly expanded edition of a book first published in 1975.

Snow is a foam of ice. It shows a brittle to ductile transition (activation energy 0.6eV) as function of strain rate and temperature. Measured values of the fracture toughness KIc in the brittle regime are used in a theory of slab avalanches.
