Fracture mechanics of micro samples: Fundamental considerations [PDF]
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 ...

Linear Elastic Fracture Mechanics Characterization of an Anisotropic Shale. [PDF]
Sci Rep, 2018 The existence of bedding planes in natural shale formations makes the fracture characterization remarkably complicated. To achieve a further understanding of the anisotropic crack extension behaviors of shale using a linear elastic fracture mechanics ...

Journal of Rock Mechanics and Geotechnical Engineering, 2019 HYDROCK method aims to store thermal energy in the rock mass using hydraulically propagated fracture planes. The hydraulic fractures can interact with the pre-existing natural fractures resulting in a complex fracture network, which can influence the ...

Breakdown of continuum fracture mechanics at the nanoscale. [PDF]
Sci Rep, 2015 Materials fail by the nucleation and propagation of a crack, the critical condition of which is quantitatively described by fracture mechanics that uses an intensity of singular stress field characteristically formed near the crack-tip.

A comparative review of peridynamics and phase-field models for engineering fracture mechanics
Computational Mechanics, 2022 Computational modeling of the initiation and propagation of complex fracture is central to the discipline of engineering fracture mechanics. This review focuses on two promising approaches: phase-field (PF) and peridynamic (PD) models applied to this ...

Quantized fracture mechanics [PDF]
Philosophical Magazine, 2004 A new energy-based theory, quantized fracture mechanics (QFM), is presented that modifies continuum-based fracture mechanics; stress- and strain-based QFM analogs are also proposed. The differentials in Griffith's criterion are substituted with finite differences; the implications are remarkable.
