A. Zinoviev,A. Zinoviev,Olga Zinovieva,Olga Zinovieva,Vasily Ploshikhin,Varvara Romanova,Varvara Romanova,Ruslan Balokhonov,Ruslan Balokhonov +8 more
TL;DR: In this article, a two-dimensional numerical model was developed to simulate the evolution of grain structure observed during the laser additive manufacturing process, where a cellular automata method was used to describe grain growth and the Goldak heat source model was adopted to calculate the heat input during laser melting.
Journal ArticleDOI
The computational micromechanics of materials with porous ceramic coatings
TL;DR: In this paper, a finite difference mesh generation procedure for an explicit account of curvilinear pore-coating and coating-substrate interfaces is developed, and a microstructure-based numerical simulation is performed by the finite difference method.
Journal ArticleDOI
A solution to the problem of the mesh anisotropy in cellular automata simulations of grain growth
O. Zinovieva,O. Zinovieva,A. Zinoviev,A. Zinoviev,Vasily Ploshikhin,Varvara Romanova,Varvara Romanova,Ruslan Balokhonov,Ruslan Balokhonov +8 more
TL;DR: Simulation results obtained for the cases of single grain growth and evolution of polycrystalline structure during solidification of alloys have demonstrated that the proposed corrections enable the mesh anisotropy problem to be solved.
Proceedings ArticleDOI
Modeling of 3D microstructures produced by additive manufacturing
V. Romanova,O. Zinovieva,R. Balokhonov,A. Zinoviev,Vasily Ploshikhin,E. Emelianova,M. Sergeev. +6 more
TL;DR: In this paper, two approaches to simulating microstructures typical of additively manufactured (AM) materials are presented, one based on the mathematical description of the microstructure evolution during metal AM process, taking into account complex physical processes involved.
Proceedings ArticleDOI
On the numerical simulation of the microstructural evolution induced by laser additive manufacturing of steel products
TL;DR: In this article, a numerical model is developed to simulate the microstructural evolution during a laser additive manufacturing process, based on original algorithms designed with the use of a modified cellular automata method proposed by Rappaz and Gandin.
