“…It is known that the first plastic deformation zones are formed near the tip of the concentrator (a notch) [18][19][20]. Their advancement in the volume of the material leads to the activation of shear displacement of grains in the elastically-plastically deformed portions of the specimen material.…”

By example of steel 17G1S, the regularities in the impact fracture of Charpy specimens at normal and low temperatures are described. The relationship between the energy parameters of fracture (impact toughness) and the deformation response of the material (the height of shear lips) of the specimens from the pipe steel is established. The micromechanisms of impact fracture of the material are described. At 20 °C and -30 °C, focal splitting of the material was observed on the fracture surface of specimens; at -60 °C, the material failed in a brittle manner by the mechanism of cleavage.

“…Their advancement in the volume of the material leads to the activation of shear displacement of grains in the elastically-plastically deformed portions of the specimen material. An elementary act of plastic yielding in this case is "shift + turn" [19]. This mechanism is due to the accommodation of local strains in the material sections.…”

Abstract. Mesoscale surface deformation in polycrystalline aluminum alloys subjected to uniaxial tension is numerically investigated. Three-dimensional polycrystalline models with equiaxial and extended grains peculiar to rolling are constructed by a step-by-step packing method. Calculation results have shown that the grain structure is responsible for the mesoscale surface roughening under uniaxial tension. The roughness pattern is affected by the microstructure and loading conditions. In a specimen with equiaxial grains and in a textured material loaded across the rolling direction surface relief is very pronounced in comparison with the extended grain structure loaded along rolling direction.

Abstract. Wilkins' method has been successfully used since early 60s for numerical simulation of high velocity contact elastic-plastic flows. The present work proposes some effective modifications of this method including more sophisticated material model including the Baushinger effect; modification of the algorithm based on correction of the initial configuration of a solid; a contact algorithm based on the idea of a mild contact.
