Strain rate dependency of dislocation plasticity [PDF]
Nature Communications, 2021 AbstractDislocation glide is a general deformation mode, governing the strength of metals. Via discrete dislocation dynamics and molecular dynamics simulations, we investigate the strain rate and dislocation density dependence of the strength of bulk copper and aluminum single crystals.

Properties of softening materials and definitive relations for uni-axial stress state
Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007 Basing on the results obtained from the research of modified Masing mode, which allows prediction the declining branch on the diagram of material straining, we partition three classes of materials: elastic-fragile, elastic-plastic and part-plastic.
