No. of bitstreams: 1 TeseBaldez.pdf: 2205858 bytes, checksum: a23b2f1dea8d7cc85600e36fce5fb295 (MD5) Previous issue date: 2012-08-27 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes) / In this thesis we study the transverse contact problem to Timoshenko beam' to elastic and thermoelastic model, whose the vertical displacement is restricted, with Signorini's contact condition. We make the mathematical modelling and well-posed model. We consider the discrete model and we make the computational modelling to the problem. The main result this work is to model the transverse contact problem and to show the qualitative properties of solution, for example, the exponential decay for energy of the system. We obtain numeric convergence rates to numeric solutions, and that enabled us to obtain numerical and computationally properties. / Nesta tese estudamos o problema de contacto transversal de uma viga, de Timoshenko, com propriedades elástica e termoelástica, restrita ao seu movimento transversal, com condição de contacto do tipo Signorini. Fazemos a modelagem matemática do problema mostrando a boa colocação do modelo. Discretizamos o modelo e fazemos a modelagem computacional do problema. O ponto alto de nosso trabalho consiste em modelar o problema de contacto transversal e mostrar as propriedades qualitativas da solução como, por exemplo, o decaimento exponencial da energia. Obtemos taxa de convergência da solução numérica, com esse resultado, tornou-se possível obter as propriedades numéricas e computacionais.
