Development of a formalism of discrete element method to study mechanical response of geological materials and media at different scales
(CIMNE, 2013)
Conference report
Open AccessA general approach to realization of models of elasticity, plasticity and fracture of heterogeneous materials within the framework of particle-based discrete element method is proposed in the paper. The approach is based ... -
Development of discrete element approach to modeling heterogeneous elastic-plastic materials and media
(CIMNE, 2011)
Conference report
Open AccessA general approach to realization of models of elasticity and plasticity of isotropic materials within the framework of discrete element method (DEM) is proposed in the paper. It is based on building many-body potentials/forces ... -
Development of multiscale approach to modeling mechanical response of high-strength intermetallic alloys on the basis of movable cellular automaton method
(CIMNE, 2013)
Conference report
Open AccessOn the basis of movable cellular automaton method (MCA) was developed a multiscale two-dimensional structural and rheological model of hard-strength intermetallic alloy Ni3Al. In this model, the intermetallic alloy is ... -
Features of interface formation in crystallites under mechanically activated diffusion. A molecular dynamics study.
(CIMNE, 2015)
Conference lecture
Open AccessIn this paper, we carried out investigation of behavior of the material under loading condition identical those used in FSW using molecular dynamic method. The loading was modelled by a rigid rotating “tool” that movies ... -
Investigation of dilatancy in block-structured geological medium on the base of movable cellular automaton method
(CIMNE, 2011)
Conference report
Open AccessThe peculiarities of dilatancy processes in block-structured media that experience nonequiaxial compression under shear deformation are investigated using movable cellular automaton (MCA) method. For a characteristic of ... -
Simulation of the mechanical response of fluidsaturated porous medium with hybrid cellular automaton method
(CIMNE, 2013)
Conference report
Open AccessThe connected physical-mechanical model of fluid-saturated porous medium, based on the coupling of particle method and net method, has been proposed. The model has been applied to simulation of the mechanical response of ... -
Theoretical investigation of the dynamics of friction stir welding process by movable cellular automaton method
(CIMNE, 2015)
Conference report
Open AccessThe paper is devoted to development of a new approach to study of friction stir welding (FSW) process on the mesoscopic scale. This approach is based on computer-aided simulation by movable cellular automaton (MCA) method. ...
