RESUMO :  As microestruturas de alguns materiais sao manipuladas adicionando novos constituintes, a fim de melhorar suas propriedades. Dessa forma, tem sido uma preocupacao constante nesses estudos a introducao de modelos representativos do comportamento do material, para que o comportamento global da estrutura possa ser representado de uma maneira mais precisa e com menor custo computacional. Este trabalho apresenta uma revisao sistematica de estudos que investigaram vantagens e desvantagens em desenvolver modelos numericos por meio de Metodos de Elementos de Contorno (MEC) em relacao a utilizar Metodos de Elementos Finitos (MEF) e/ou acoplamento MEC/MEF em analise nao-linear de placas compostas por materiais heterogeneos atraves de uma abordagem em multiescala utilizando Elementos de Volume Representativo (EVR). As fontes de pesquisa foram as seguintes bases de dados indexadas: Portal de Periodicos da Coordenacao de Aperfeicoamento de Pessoal de Nivel Superior (CAPES), Scopus, Conpemdex e Science Direct. Cabe destacar que a aplicacao do Mapeamento Sistematico na elaboracao de revisao bibliografica permitiu identificar as principais lacunas para o desenvolvimento de novas pesquisas, alem disso, direciona para as principais publicacoes ligadas ao estudo. Por fim, os resultados obtidos fornecem, de um lado, subsidios para formulacao em multiescala apenas atraves do MEC e, de outro, evidenciam os resultados comparados com aqueles obtidos atraves da analise onde se faz o acoplamento MEC/MEF, a fim de verificar os resultados numericos e indicar as vantagens e desvantagens dos dois tipos de modelagens. ABSTRACT : The microstructures of some materials are manipulated by adding new constituents in order to improve their properties. Thus, it has been a constant concern in these studies the introduction of representative models of the behaviour of the material, so that the overall behaviour of the structure can be represented in a more precise and lower computational cost. This work presents a systematic review of studies that have investigated advantages and disadvantages in developing numerical models through the methods of contour elements (BEM) in relation to using finite element methods (FEM and/or BEM/FEM coupling in non-linear analysis of plates composed by heterogeneous materials through a multiscale approach using representative Volume elements (RVE). The research sources were the following indexed databases: The Portal of periodicals for the coordination of improvement of staff of higher level (CAPES), Scopus, Conpemdex and Science Direct. It is important to highlight that the application of systematic mapping in the elaboration of bibliographical revision has allowed to identify the main gaps for the development of new research, in addition, directs to the major publications related to the study. Finally, the results obtained provide, on the one hand, subsidies for multiscale formulation only through BEM and, in addition, they demonstrate the results compared to those obtained through the analysis where the MEC/MEF coupling is made in order to verify the numerical results and indicate the advantages and disadvantages of the two types of modeling.
