Resumen:
The very recently introduced Virtual Element Method (VEM) is a numerical method forsolving partial differential equations that was created out of the mimetic difference method, but was laterreformulated into the Galerkin framework. It is a generalization of the standard Finite Element Method(FEM) to general meshes made up by arbitrary polyhedra. The greatest advantage of VEM is to be ableto deal with very complex geometries, i.e., made up by elements of any number of edges not necessarilyconvex, hanging nodes, flat angles, collapsing nodes, etc, while retaining the same approximationproperties of FEM. In this paper we propose the simulating of the mechanical response of cement-basedcomposites by means of a Virtual Element approach for discretization of the domain, along with a novelinteraction between zero-thickness interface element for meso-scale analysis within the framework ofthe so-called discontinuous-based approach. Following a similar modeling approach already availablein literature for FEM and iso-parametric interface elements, the formulation of the VEM for elasticityproblems is a novelty that can be used to capture the key mechanical phenomena controlling concreteheterogeneity by taking advantage of the versatility of polyhedral meshes.
