Relating plasticity to dislocation properties by data analysis: scaling vs. machine learning approaches

Stefan Hiemer, Haidong Fan, Michael Zaiser

Plasticity modelling has long been based on phenomenological models based on ad-hoc assuption of constitutive relations, which are then fitted to limited data. Other work is based…

Nonsymmorphic nodal-line metals in the two-dimensional rare earth monochalcogenides MX (M = Sc, Y; X = S, Se, Te)

Hao Guo, Jianzhou Zhao, Cong Chen +4

We predict a new family of two-dimensional (2D) rare earth monochalcogenide materials MX (M = Sc, Y; X = S, Se, Te). Based on first-principles calculations, we confirm their stabil…

Strain rate dependency of dislocation plasticity

Haidong Fan, Jaafar A. El-Awady, Qingyuan Wang +2

Dislocation slip is a general deformation mode and governs the strength of metals. Via discrete dislocation dynamics and molecular dynamics simulations, we investigate the strain r…

Grain boundary effect on nanoindentation: A multiscale discrete dislocation dynamics model

Songjiang Lu, Bo Zhang, Xiangyu Li +4

Nanoindentation is a convenient method to investigate the mechanical properties of materials on small scales by utilizing low loads and small indentation depths. However, the effec…

Microplasticity and yielding in crystals with heterogeneous dislocation distribution

Xu Zhang, Jian Xiong, Haidong Fan +1

In this study, we use discrete dislocation dynamics (DDD) simulation to investigate the effect of heterogeneous dislocation density on the transition between quasi-elastic deformat…

Anomalous Hardening in Magnesium Driven by a Size-Dependent Transition in Deformation Modes

Gi-Dong Sim, Gyuseok Kim, Steven Lavenstein +3

Magnesium (Mg) and its alloys hold great potential as an energy-saving structural material for automative, aerospace applications. However, the use of Mg alloys has been limited du…
