Variational approach to determine the properties of dislocations at finite deformation
István Groma
A generalised version of the continuum theory of curved dislocations describing the spatial and temporal evolution of the fields: statistically stored dislocation density, geometri…
Dislocation distribution near a wall within the framework of the continuum theory of curved dislocations
István Groma, Dénes Berta, Lóránt Sándli +1
A recently proposed generalised continuum theory of curved dislocations describes the spatial and temporal evolution of statistically stored and geometrically necessary dislocation…
Irreversible evolution of dislocation pile-ups during cyclic microcantilever bending
Dávid Ugi, Kolja Zoller, Kolos Lukács +5
In metals geometrically necessary dislocations (GNDs) are generated primarily to accommodate strain gradients and they play a key role in the Bauschinger effect, strain hardening,…
Statistical analysis of dislocation cells in uniaxially deformed copper single crystals
Sándor Lipcsei, Szilvia Kalácska, Péter Dusán Ispánovity +3
The dislocation microstructure developing during plastic deformation strongly influences the stress-strain properties of crystalline materials. The novel method of high resolution…
Irradiation-induced strain localization and strain burst suppression investigated by microcompression and concurrent acoustic emission experiments
Dávid Ugi, Gábor Péterffy, Sándor Lipcsei +4
Plastic deformation of microsamples is characterised by large intermittent strain bursts caused by dislocation avalanches. Here we investigate how ion irradiation affects this phen…
Dislocation Avalanches: Earthquakes on the Micron Scale
Péter Dusán Ispánovity, Dávid Ugi, Gábor Péterffy +7
Compression experiments on micron-scale specimens and acoustic emission (AE) measurements on bulk samples revealed that the dislocation motion resembles a stick-slip process - a se…
