Estudo das trincas com o Método dos Elementos de Contorno utilzando Função de Green Numérica e a Técnica da Dupla Reciprocidade

Abstract

In Recent years, various mathematical tools were developed to solve problems involving the mechanics of linear elastic fracture to static Cases and to Dynamic Case. The Boundary Element Method, the technique of double Reciprocity and a Green Function Numerical has been successfully applied to problems with field actions (for example: Gravitational forces, transient Problems with speeds and accelerations). With these basic tools, this work presents Complementary Studies using the Boundary Element Method, a numerical Green function technique, along with the technique of Dual Reciprocity. This work numerically analyzing the e˙ect of a concentrated load in a particular beam, the field of action with the self-weight and load applied both in the positive and in the negative direction of the Cartesian axis y.
