Crack nucleation in circular disk under mixed boundary conditions
Archives of Mechanics, 2015 A model of crack nucleation in a circular disk, based on consideration of cracking process zone is suggested. It is assumed that the cracking process zone is a finitelength layer containing a material with partially disturbed bonds between separate ...

Crack growth modelling: enriched continuum vs. discrete models [PDF]
, 2015 Failure in quasi-brittle materials usually appears in the form of narrow bands called fracture process zones, where all inelastic deformation takes place, while the surrounding bulk material outside those areas typically unloads elastically.

Fracture process zone in granite: a microstructural analysis
International Journal of Earth Sciences, 2001 Shear fracture propagation in rock is accompanied by localized microcracking in a process zone surrounding the fracture tip. We investigated the crack microstructures along experimentally formed shear fractures from four granite samples (uniaxial compression tests).

Cleaved surface of i-AlPdMn quasicrystals: Influence of the local temperature elevation at the crack tip on the fracture surface roughness [PDF]
, 2006 Roughness of i-AlPdMn cleaved surfaces are presently analysed. From the atomic scale to 2-3 nm, they are shown to exhibit scaling properties hiding the cluster (0.45 nm) aperiodic structure.

Molecular Dynamics-Based Cohesive Zone Model for Mg/Mg17Al12 Interface
Metals, 2020 The fracture of the Mg/Mg17Al12 interface was investigated by molecular dynamics simulations. The interface crack extends in a brittle manner without noticeable plasticity.

Nonlocal Criteria for Brittle and Quasi-Brittle Fracture of Geomaterials and Rocks
E3S Web of Conferences, 2018 Nonlocal criteria are used for prediction materials and rock mass failure near stress concentrations (pores, faults, openings, excavations). A common property of nonlocal fracture criteria is the introduction of the intrinsic material length ...

Mechanical performance of glass-based geopolymer matrix composites reinforced with cellulose fibers [PDF]
, 2018 Glass-based geopolymers, incorporating fly ash and borosilicate glass, were processed in conditions of high alkalinity (NaOH 10-13 M). Different formulations (fly ash and borosilicate in mixtures of 70-30 wt% and 30-70 wt%, respectively) and physical ...
