Universality of Avalanche Exponents in Plastic Deformation of Disordered Solids
Zoe Budrikis, David Fernandez-Castellanos, Stefan Sandfeld +2
Plastic yield of amorphous solids occurs by power law distributed slip avalanches whose universality is still debated. Determination of the power law exponents from experiments and…
Continuum Representation of Systems of Dislocation Lines: A General Method for Deriving Closed-Form Evolution Equations
Mehran Monavari, Stefan Sandfeld, Michael Zaiser
Plasticity is governed by the evolution of, in general anisotropic, systems of dislocations. We seek to faithfully represent this evolution in terms of density-like variables which…
Local density approximation for the energy functional of three-dimensional dislocation systems
Michael Zaiser
The elastic energy functional of a system of discrete dislocation lines is well known from dislocation theory. In this paper we demonstrate how the discrete functional can be used…
Statistical Analysis and Stochastic Dislocation-Based Modelling of Microplasticity
Olga Kapetanou, Vasilis Koutsos, Efstathios Theotokoglou +2
Plastic deformation in microscale differs from the macroscopic plasticity in two respects: (i) the flow stress of small samples depends on their size (ii) the scatter of plasticity…
Pattern formation in a minimal model of continuum dislocation plasticity
Stefan Sandfeld, Michael Zaiser
The spontaneous emergence of heterogeneous dislocation patterns is a conspicuous feature of plastic deformation and strain hardening of crystalline solids. Despite long-standing ef…
