Plastic yielding and deformation bursts in the presence of disorder from coherent precipitates
Henri Salmenjoki, Arttu Lehtinen, Lasse Laurson +1
Alloying metals with other elements is often done to improve the material strength or hardness. A key microscopic mechanism is precipitation hardening, where precipitates impede di…
Excitation spectra in crystal plasticity
Markus Ovaska, Arttu Lehtinen, Mikko J. Alava +2
Plastically deforming crystals exhibit scale-free fluctuations that are similar to those observed in driven disordered elastic systems close to depinning, but the nature of the yie…
Multi-scale modeling of dislocation-precipitate interactions in Fe: from molecular dynamics to discrete dislocations
Arttu Lehtinen, Fredric Granberg, Lasse Laurson +2
The stress-driven motion of dislocations in crystalline solids, and thus the ensuing plastic deformation process, is greatly influenced by the presence or absence of various point-…
