The multiple collapse mechanisms of complex materials produced by additive manufacturing (AM) were identified by measurements of the acoustic emission (AE) of the …
Crackling noise is a scale-invariant phenomenon found in various driven nonlinear dynamical material systems as a response to external stimuli such as force or external fields …
The intermittent plasticity of pure Mo microcrystals with diameters from 500 to 3500 nm was studied using micro-pillar compression methodology at temperatures ranging from 25° C to …
Slip intermittency and stress oscillations in titanium alloy Ti–7Al–O that were observed using in-situ far-field high energy X-ray diffraction microscopy (ff-HEDM) are investigated using a …

The increase in the yield stress due to the presence of obstacles to dislocation motion such as precipitates is a multiscale phenomenon. The details on the nanoscale when an …
We demonstrate the gradual shift from scale-free intermittent microplasticity to a scale- dependent behavior via the introduction of a variety of microstructural features within the Al …
In this work, we present a three-dimensional ab-initio informed phase-field-dislocation dynamics model combined with Langevin dynamics to investigate glide mechanisms of …
