Sistema gráfico interativo para ensino de análise estrutural através do método dos elementos finitos

Abstract

This masters thesis refers to the expansion of INSANE (INteractive Structural ANalysis Environment): a computational system for finite element method (FEM) structural analysis discrete models, in Java language and object oriented programming (OOP). The work consists in an interactive graphic application to assist the FEM teaching for structuralengineering. A study of the diverse approaches for FEM in engineering courses is presented, identifying its generalities and the possibilities that INSANE oers to facilitate learning process. It is argued, then, available suggestions in literature for characterization of stages for the solution of FEM problems. It is verified that the OOP is quite appropriated for the implementation and the use of language Java has great advantages. An object oriented analysis to identify the main necessary classes for exposition of the numerical nucleus of the computational system tothe user is done. This work documents and focuses on object-oriented Analysis, Project and Implementation. Admittedly ecient software design patterns are adopted in the implementation of the application. To separate the model from its representation, the implementation isbased on Model-View-Controller (MVC) programming metaphor. Such approach allows the graphical, interactive and didactic presentation of the processing of FEM models. The implementations object oriented project is shown with unified modelling language (UML). The resources of the new graphical interface are presented through examples and thepossibilities of enrichment of the learning process are shown.
