No. of bitstreams: 1 danielalexisgutierrezpachas.pdf: 1333600 bytes, checksum: f9b6cf486d282ebbca315b17f7d4c92c (MD5) Previous issue date: 2013-01-29 / CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Neste trabalho realizamos um estudo teórico das Inequações Variacionais e sua aplicação no Problema do Obstáculo. Fazemos o estudo de regularidade para este problema, e observamos que quando as condições de regularidade são satisfeitas, o Problema do Obstáculo torna-se um Problema de Complementaridade. Apresentamos os resultados de equivalência entre o Problema do Obstáculo e o Problema do Dique Retangular. Descrevemos o funcionamento do Algoritmo FDA-NCP, e resolvemos numericamente o Problema do Obstáculo usando complementaridade. / In this work, we perform a theoretical study on Variational Inequalities and their application to the Obstacle Problem. We study the regularity for this problem, and observe that when the regularity conditions are satis ed the Obstacle Problem becomes a Complementarity Problem. We present the equivalence results between the Obstacle Problem and the Square Dam Problem. We describe how the algorithm FDA-NCP works and numerically to solve the Obstacle Problem employing complementarity.
