However, this technology imposes a new level of difficulties to manufacturers, since small variabilities in the manufacturing of composite components have a high influence on the effective properties of the product. The objective of this work consists of a methodology to evaluate composite materials manufacturing process to identify components out of specification. For this, it is necessary to understand the influence of design variables on the dynamic behaviour of a specimen, construct a numerical model to represent the specimens and develop criteria to classify the analysed specimens. To achieve these goals, the research methodology should consider the use of methods like the design of experiments, Kriging model update, and vibration-based methods. First, the geometrical characteristics of the composite plates are evaluated by a 3D scanner machine. In addition, the materials properties presented in the literature are listed to define an approximate range where the real values have more probability to be present. Afterward, a Design of Experiments (DoE) is used for screening the variables and evaluate the main effect of each variable on each vibrational mode. The DoE results are used as base information to a model update procedure that results on the estimated materials properties and a refined numerical model. In this work, the model update process is improved using Kriging metamodel aiming to reduce the computational time required. Finally, the updated numerical model is used to obtain the FRFs that composes the envelope representing the composite plate set. This envelope can help engineers to evaluate other composite plates and classify them accordingly to the design specifications. The proposed methodology presented relevant results, by defining the main variables that influence the dynamic behaviour and supporting the model update process resulting in errors in the order of 1 and 2%. Besides the good approximation, the model update process using Kriging was efficient in terms of computational time, requiring half of the time when compared with a methodology without using metamodels. Finally, it is discussed the advantages and limitations of the applicability of this methodology in the presentation of two case studies.Exigências do sistema: Adobe Acrobat ReaderMedeiros, Ricardo,1963- OrientadorUniversidade do Estado de Santa Catarina.Programa de Pós-Graduação em Engenharia MecânicaSouza, Luiz Fernando dos Santos2018info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesishttp://sistemabu.udesc.br/pergamumweb/vinculos/000053/00005362.pdfengTexto em inglês com resumo em portuguêsreponame:Biblioteca Digital de Teses e Dissertações da UDESCinstname:Universidade do Estado de Santa Catarinainstacron:UDESCinfo:eu-repo/semantics/openAccess2019-05-11T18:42:30Zmail@mail.com -
