No. of bitstreams: 1 2016 - Marlon Ferreira Corsi.pdf: 1024630 bytes, checksum: b658b25c24b2a05e620598b506dc2907 (MD5) Previous issue date: 2016-03-28 / 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. / Nos ?ltimos anos, v?rias ferramentas matem?ticas foram desenvolvidas para se resolver problemas que envolvam a mec?nica da fratura linear el?stica (MFLE) tanto para casos est?ticos quanto para casos din?micos. O M?todo dos Elementos de Contorno (MEC), a t?cnica da Dupla Reciprocidade e a Fun??o de Green Num?rica tem sido aplicado com sucesso ? problemas com a??es de dom?nio (por exemplo: for?as gravitacionais, problemas transientes com velocidades e acelera??es). Com base nessas ferramentas, este trabalho apresenta estudos complementares utilizando o M?todo do Elemento de Contorno (6), a t?cnica da Fun??o de Green num?rica (9), junto com a t?cnica da Dupla Reciprocidade (11). Esse trabalho analisa numericamente o efeito de uma carga concentrada em uma determinada viga, a a??o do dom?nio com o peso pr?prio, e o carregamento aplicado tanto no sentido positivo quanto no sentido negativo do eixo cartesiano y.
