Vigas e placas espessas em base elástica de Kerr: fomulações do método dos elementos de contorno

Abstract

Studies of single or double structural systems have been constantly developed by many researchers, due to their extensive practical application in engineering problems. A breve review of the literature shows the most common elastic layer used are Winkler and Pasternak models. Surprisingly, few studies deal with the Kerr elastic layer. Commonly, exact or FEM solutions are used to solve these problems. This thesys presents the direct Boundary Element Method (BEM) formulation for bending analysis the beams and thick plates on Kerr layer and double-beam system connected by a Kerr elastic layer. Fundamental solutions, integral equations and algebraic equations are derived and explicitly shown. Presented numerical results in this thesis shows the accuracy of the technique and the elegance of the solutions proposed.
