Analysis of the constitutive response of heterogeneous materials by the boundary element method, considering different RVE microstructuresAnálise da resposta constitutiva de materiais heterogêneos pelo método dos elementos de contorno, considerando-se diferentes microestruturas para o EVR
(2020-01-01)
Numerical analyses to model the constitutive response of heterogeneous materials by a Boundary Element Formulation, developed in the context of a RVE-based multi-scale theory, are performed. In this case, the material ...
A 2D boundary element formulation to model the constitutive behavior of heterogeneous microstructures considering dissipative phenomena
(2019-02-01)
A boundary element formulation to obtain the constitutive response of heterogeneous microstructures is proposed, considering a RVE-based multiscale theory. The sub-region technique is adopted to model the RVE (Representative ...

An RVE-based multiscale theory of solids with micro-scale inertia and body force effects
(Elsevier, 2015-01)
A multiscale theory of solids based on the concept of representative volume element (RVE) and accounting for micro-scale inertia and body forces is proposed. A simple extension of the classical Hill–Mandel Principle together ...
A 2D BEM formulation considering dissipative phenomena and a full coupled multiscale modelling
(2020-10-01)
A full coupled multi-scale modelling using the Boundary Element Method for analysing the 2D problem of stretched plates composed of heterogeneous materials, where dissipative phenomena can be considered, is presented. Both ...
A boundary element formulation to perform elastic analysis of heterogeneous microstructures
(2018-02-01)
A BEM formulation to perform elastic analysis of heterogeneous microstructures is proposed in the context of multi-scale analysis. The microstructure, also denoted as RVE (Representative Volume Element), is modeled as a ...
Effective properties of nodular cast-iron: A multi-scale computational approach
(Elsevier Science, 2014-02)
A numerical approach based on a computational constitutive multi-scale model is used in this work to predict the effective Young’s modulus and Poisson’s ratio of a pearlitic nodular cast iron. The Representative Volume ...
Thermal expansion of a Spheroidal Graphite Iron: A micromechanical approach
(Elsevier Science, 2018-03)
Dimensional variations experienced by materials due to temperature changes are described by the Coefficient of Thermal Expansion (CTE), which is strongly dependent on microstructural features, especially on composites ...
Partição de deformação em aços dual-phase
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2022-09-29)
The tailoring of new alloys often requires improvement in strength, for performance, and ductility to support mechanical processing until the final shape is achieved. Important advances have been obtained in the last decades ...
