Micromodelamiento mecánico de un acero doble fase mediante un RVE 3D generado por teselaciones de Voronoi

Abstract

The aim of this project is to show the mechanical micromodeling of a dual-phase steel by means of an RVE generated by Voronoi tessellations. generated by Voronoi tessellations, for which in a first instance it will be shown the problems, justification and objectives the problems, justification and objectives to be achieved with this project, then, the state of the art related to the simulation of materials and construction of representative volumes from Voronoi tessellations will be presented, then, the experimental procedure will be explained, going through the construction of the RVE, configuration of the material properties, simulations and obtaining the results; Finally, the results will be presented with their respective analyses, in which the stress-strain diagrams (when loading the RVE in different directions), the modulus of elasticity, the stress distributions, the behavior of the microconstituents of the steel and a comparison with the results of a 2D simulation will be determined.
