This study describes the internal structure of materials used to produce medical stents. A two-level elastoviscoplastic mathematical model, which sets the parameters and describes the processes at the grain level, was developed and numerically implem

The paper discusses problems related to the description of metals and alloys internal structure. By classical molecular dynamics simulation, we developed and numerically implemented mathematical model to describe a microcracks and edge dislocations t

The work is dedicated to describing and modeling of the damage formation process near a boundary of two adjacent grains in α−Ti alloy. The main microdamage mechanism near grain boundary was the stress field of a dislocation pile-up in one grain. A

The paper addressed issues related to the description of the internal structure of metals and alloys in terms of microvoids nucleation and evolution, which are one of the varieties of damages. By classical molecular dynamics simulation we develop and

This article considers the issues related to the correct description of the internal structure of grain boundaries in metals. We offered a mathematical model describing grain boundaries formation as a result of two-sided crystallization by applying m

This paper reports the research results on the continuum theory of damage which goes back to the works of Kachanov, Gurson, and Rabotnov. In these models, internal variables that generally have different mathematical structure are explicitly introduc

This paper completes the review of recent (last 15 years) publications on experimental and theoretical methods and approaches for studying damage accumulation and fracture in crystalline solids. It summarizes the works that describe damage and fractu

This paper discusses multiscale models of inelastic deformation of single- and polycrystals, which are based on crystal plasticity theories, as applied to the verification and justification of Ilyushin’s isotropy postulate (in a special form) at la
