Preparo de um Programa de Elementos Finitos para Análise Dinámica de Estruturas por Subestruturação

Abstract

This work has the objective of prepare a computacional program needful to the application of the substructure method that has support of a cientific finite element method program, which permit the dinamic analysis of large structures through a numerical problem of a reduced size. It is utilized the Component Modes Synthesis (Hurty) (that result with a simetric mass matrix which became diagonal by a coordenate transformation), Two examples are shown and their results
are compared with finite element method.
