Nucleation of interfacial shear cracks in thin films on disordered substrates
Michael Zaiser, Paolo Moretti, Avraam Konstantinidis +1
We formulate a theoretical model of the shear failure of a thin film tethered to a rigid substrate. The interface between film and substrate is modeled as a cohesive layer with ran…
Depinning and critical current characteristics of topologically defected vortex lattices
Paolo Moretti, M. -Carmen Miguel
We discuss the role of dislocation assemblies such as grain boundaries in the dynamic response of a driven vortex lattice. We simulate the depinning of a field-cooled vortex polycr…
Dislocation interactions mediated by grain boundaries
Paolo Moretti, Lasse Laurson, Mikko J. Alava
The dynamics of dislocation assemblies in deforming crystals indicate the emergence of collective phenomena, intermittent fluctuations and strain avalanches. In polycrystalline mat…
Fluctuation phenomena in crystal plasticity - a continuum model
Michael Zaiser, Paolo Moretti
On microscopic and mesoscopic scales, plastic flow of crystals is characterized by large intrinsic fluctuations. Deformation by crystallographic slip occurs in a sequence of interm…
Grain boundaries in vortex matter
Paolo Moretti, M. -Carmen Miguel, Stefano Zapperi
We explore the statistical properties of grain boundaries in the vortex polycrystalline phase of type II superconductors. Treating grain boundaries as arrays of dislocations intera…
Depinning transition of dislocation assemblies: pileup and low-angle grain boundary
Paolo Moretti, M. -Carmen Miguel, Michael Zaiser +1
We investigate the depinning transition occurring in dislocation assemblies. In particular, we consider the cases of regularly spaced pileups and low angle grain boundaries interac…
