Evolution of the grain structure of metals and alloys under severe plastic deformation: continuum models
Autor: P. V Trusov, T. V Ostanina, A. I Shveykin
Publikováno v: PNRPU Mechanics Bulletin. :123-155
Products made of metals and alloys with a fine-grained structure, which have high physical, mechanical and operational characteristics, are becoming increasingly in demand in many technical and technological fields. The most common and efficient tech

Evolution of the grain structure of metals and alloys under intense plastic deformation: multilevel models
Autor: P. V Trusov, T. V Ostanina, A. I Shveykin
Publikováno v: PNRPU Mechanics Bulletin. :114-146
It is well known that the performance properties of products made of metals and alloys are determined mainly by the meso- and microstructure of the latter. The structure of materials is formed and undergoes significant changes in the processes of man

Multilevel Model for the Description of Plastic and Superplastic Deformation of Polycrystalline Materials
Autor: E. R. Sharifullina, A. I. Shveykin, P. V. Trusov
Publikováno v: Physical Mesomechanics. 22:402-419
Superplastic forming is promising for the manufacturing of complex-shaped metal parts and components. Superplastic conditions allow one to produce unwelded parts, to reduce the number of technological operations and forming forces, and thus to reduce

Statistical crystal plasticity model of commercially pure titanium: Validation and estimation of sensitivity to impacts perturbations
Autor: Kirill A. Romanov, Alexey I. Shveykin
Publikováno v: 29TH RUSSIAN CONFERENCE ON MATHEMATICAL MODELLING IN NATURAL SCIENCES.
A two-level statistical constitutive model of commercially pure titanium with hcp is considered. A series of computational experiments for uniaxial loadings with different set of mechanisms taken into account was carried out. The model identification

Multi-level direct crystal plasticity model of polycrystalline specimen: Grains generation
Autor: Anton Yu. Yants, A. A. Tokarev, Nikita S. Kondratiev, Alexey I. Shveykin
Publikováno v: 29TH RUSSIAN CONFERENCE ON MATHEMATICAL MODELLING IN NATURAL SCIENCES.
A partially polycrystalline specimen generation method is presented. It is based on polycrystalline geometrical description package Neper, which provides optimal polyhedral description of polycrystals from experimental properties. The method allows t

Investigation of HCP metal mesolevel model sensitivity to lattice orientation perturbations
Autor: Alexey I. Shveykin, Kirill A. Romanov
Publikováno v: 28TH RUSSIAN CONFERENCE ON MATHEMATICAL MODELLING IN NATURAL SCIENCES.
The main element of two-level constitutive models of polycrystalline hcp metals is the mesolevel relations. An algorithm for assessing of the mesolevel model response (stress history) sensitivity to the initial crystallite lattice orientation perturb

Three-level model for description of polycrystal superplastic deformation
Autor: E. R. Sharifullina, A. I. Shveykin, Peter V. Trusov
Publikováno v: 28TH RUSSIAN CONFERENCE ON MATHEMATICAL MODELLING IN NATURAL SCIENCES.
We proposed a modified statistical multilevel model based on crystal plasticity, which allows describing deformation of polycrystalline metals with transition to structural superplasticity regime. The main mechanisms of plastic and superplastic defor
