Abstract

The objective of this work is to present a research project, which is one of the requirements to request a BEPE (Bolsa de Estágio e Pesquisa no Exterior) in England, in the Centre for Additive Manufacturing (CfAM), under the supervision of Prof. Ian Ashcroft, at the University of Nottingham, in the year of 2018, from 01 of February to 31 of July. This scholarship request is related to the FAPESP's process 2016/17835-6 in development in Brazil, at the Instituto Tecnológico de Aeronáutica (ITA), under the supervision of the Prof. Rafael Thiago Luiz Ferreira. The main purposes of the research project in England are: to study and develop models of 3D printed materials by Fused Deposition Modelling using asymptotic homogenization technique, to implement Python routines to generate microstructure models, to implement the homogenization technique in ABAQUS, to formulate and solve optimization problems that can improve stiffness and strengths of 3D printed structures. This period in England is an important opportunity to contribute to the candidate's doctorate's thesis, to increase knowledge in the asymptotic homogenization technique and additive manufacturing technologies.
