[HTML][HTML] Studying dislocation-induced shielding effect on the crack-tip in polycrystal by discrete dislocation dynamics

S Liang, Y Zhu, M Huang, Z Li - International Journal of Solids and …, 2019 - Elsevier
The dislocation-induced shielding effect on the crack-tip depends on not only the number of
dislocations but also the distance of dislocations from the crack-tip. The former is closely …

The -invariant and topological pathways to influence sub-micron strength and crystal plasticity

S Papanikolaou, G Po - arXiv preprint arXiv:1906.01482, 2019 - arxiv.org
In small volumes, sample dimensions are known to strongly influence mechanical behavior,
especially strength and crystal plasticity. This correlation fades away at the so-called …
