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…
Dislocation Dynamics and Shape in High Entropy Alloys: the Influence of Stress Correlations, Long-Range Interactions and Anisotropy
Dénes Berta, Péter Dusán Ispánovity
High entropy alloys gained significant scientific interest in recent years due to their enhanced mechanical properties including high yield strength combined with outstanding ducti…
Deciphering Acoustic Emission with Machine Learning
Dénes Berta, Balduin Katzer, Katrin Schulz +1
Acoustic emission signals have been shown to accompany avalanche-like events in materials, such as dislocation avalanches in crystalline solids, collapse of voids in porous matter…
Avalanche Dynamics and the Effect of Straining in Dislocation Systems with Quenched Disorder
Dénes Berta, Barna Mendei, Péter Dusán Ispánovity
The plastic deformation of crystalline and other heterogeneous materials often manifests in stochastic intermittent events indicating the criticality of plastic behavior. Previous…
