Geração de Malha com Elementos de Interface para Modelagem em Microestrutura Policristalina em 2D

Abstract

For interface calculation elements in polycrystalline materials for two-dimensional modeling, an algorithm was implemented, which performs an analysis through a twodimensional mesh file, which modifies using an element generator and chooses the existing grains by a predefined factor to create interface elements, facilitating the modeling of damage phenomena that occur at grain boundaries. If the mesh of the original 2D polycrystalline microstructure, modifying the mesh periodicity at the boundary of the modeling domain. This methodology automatically creates distinct granular structures that allow the mechanical properties of metals and other materials to be modeled and simulated. The importance of this methodology allows the simulation to make a variability of the fracture sampling and the mechanical properties that are observed in the experiments to be reproduced in the simulations. The resulting mesh is exported in a software-readable format from commercial Finite Element Methods and/or OpenSource.
