Physical scaling in microstructures and avalanches of dislocation by Dislocation Dynamics simulations

M Aissaoui, C Kahloun, OU Salman… - arxiv preprint arxiv …, 2024 - arxiv.org
At the mesoscale, the avalanche-like plastic bursts are associated with statistical signatures,
whose parameters are not always well defined. In this work, we performed large scale and …

On the saturation stress of deformed metals

S Queyreau - arxiv preprint arxiv:2301.00625, 2023 - arxiv.org
Crystalline materials exhibit an hysteresis behaviour when deformed cyclically. The origins
of this tension-compression asymmetry have been fully understood only recently as being …

Plastic deformation in crystalline materials is controlled by the motion and interactions of
dislocations (Anderson et al. 2017). Discrete dislocation dynamics (DDD) simulations have …

On the Origins of Tension--Compression Asymmetry in Crystals and Implications for Cyclic Behavior

S Queyreau, B Devincre - arxiv preprint arxiv:2012.15540, 2020 - arxiv.org
Most of crystalline materials exhibit a hysteresis on their deformation curve when
mechanically loaded in alternating directions. This Bauschinger effect is the signature of …
