Abstract

A novel and straightforward methodology to analyze materials under constant-structure oscillatory motion (SAOS and QL-LAOS)Dissertation presented to the Programa de Pós-graduação em Engenharia Mecânica of PUC-Rio in partial fulfillment of the requirements for the degree of Mestre em Engenharia Mecânica. Approved by the undersigned Examination Committee. Prof. Paulo Roberto de Souza Mendes Advisor Departamento de Engenharia Mecânica -PUC-Rio Prof. Roney Leon Thompson Programa de Engenharia Mecânica -COPPE -UFRJ Dr. Flávio Henrique Marchesini de Oliveira Departamento de Engenharia Mecânica -PUC-Rio Prof. Márcio da Silveira CarvalhoVice Dean of Graduate Studies Centro Técnico Científico -PUC-Rio Rio de Janeiro, September the 13th, 2017 PUC-Rio -Certificação Digital Nº 1521990/CA All rights reserved. Ricardo Teixeira LeiteRicardo Teixeira Leite graduated in Mechanical Engineering at Pontifical Catholic University of Rio de Janeiro (PUC-Rio) in 2015. Then, he started to work as a research engineer with rheology and non-Newtonian fluid mechanics in the Rheology Group (GReo) at PUC-Rio, where he was already involved in research activities for three years as an undergraduate student AcknowledgmentsI would like to first thank my advisor Paulo Roberto de Souza Mendes for our partnership along the last six years. I've learned a lot from you as an engineer and as a person. I would also like to thank Monica Nacacche for leading our research group alongside Paulo, always being a pleasent and important presence in our meetings. I'm also indebted to CNPq for providing me a scholarship and for the financial support to this research.Then, I wish to thank all my fellow coworkers at the Rheology Group. Especially my "roomates" Aline Abdu, Bruna Leopércio, Carina Beline and Priscilla Varges. Thank you, Aline, for always listening to me whine during lunch and calming me down; Bruna for our beautiful friendship that preceds and will outlive our workmate relationship; Carina for the friday afternoons (listening to sertanejo out loud); and Priscilla for interrupting all of your (MANY) tasks to help me whenever I asked you a technical question (even though I didn't intend to have that much attention to the matter). I would also like to especially thank Eliana Marin for the incredible work on our parallel research with Petrobras and for holding the fort during the time I was focused on my thesis. I would also like to thank Flávio, for introducing me to research; and Alexandra, for giving me an everyday guidance throughout my graduation, making it possible for me to continue her research. At last, for your friendship, I would like to thank Pedro, Bruno, Elias, Behbood, PH, Roberta and Tati.I believe true happiness is achieved through relationships, including the one you have with yourself. Hence, I am silently thanking every person that I eventually crossed paths with. Each of you helped me on this journey of becoming who I am today. However, I want to formally address some of those.First, I would like to thank my family. You've been by m...
