Discrete Dislocation Dynamics Modeling of Nanotwinned Materials: Orientation Effects in a Multilayer Twinned Structure of Copper
DeAn Wei, Michael Zaiser, Jing Tang +1
The impact of twin boundaries (TBs) on the microstructure evolution and plastic deformation mechanisms of face-centered cubic (FCC) metals has been extensively studied since the di…
A phase field model of the effects of dislocation microstructure on grain boundary motion during recrystallization
Yufan Zhang, Michael Zaiser
The internal energy associated with the defect microstructure of strongly deformed crystals provides an important driving force for grain boundary motion during recrystallization.…
Strengthening and toughening mechanisms in heterostructured laminates revealed by a phase field-enhanced crystal plasticity simulation
Yukai Xiong, Jianfeng Zhao, Jinling Liu +3
Heterostructured (HS) materials exhibit excellent mechanical properties, combining high strength and significant ductility. Hetero-deformation-induced (HDI) hardening and strain de…
Continuum Dislocation Dynamics as a Phase Field Theory with Conserved Order Parameters
Yufan Zhang, Ronghai Wu, Michael Zaiser
The dynamics of dislocations can be formulated in terms of the evolution of continuous variables representing dislocation densities ('continuum dislocation dynamics'). We show for…
Tuning load redistribution and damage near heterogeneous interfaces
Christian Greff, Paolo Moretti, Michael Zaiser
We investigate interface failure of model materials representing architected thin films in contact with heterogeneous substrates. We find that, while systems with statistically iso…
Creep failure of hierarchical materials
Mahshid Pournajar, Paolo Moretti, Seyyed Ahmad Hosseini +1
Creep failure of hierarchical materials is investigated by simulation of beam network models. Such models are idealizations of hierarchical fibrous materials where bundles of load-…
Size scaling of strength in thin film delamination
Michael Zaiser
We investigate by numerical simulation the system size dependence of the shear delamination strength of thin elastic films. The films are connected to a rigid substrate by a disord…
Roughening and pinning of interface cracks in shear delamination of thin films
M. Zaiser, P. Moretti, A. Konstantinidis +1
We investigate the roughening of shear cracks running along the interface between a thin film and a rigid substrate. We demonstrate that short-range correlated fluctuations of the…
