Geração automática de dados para análise de juntas tubulares de estruturas "offshore"

Abstract

The evaluation of localized stress in offshore structure tubular joints is of great importance and interest. The Finite Element Method is used to stress analysis but the non-automatic mesh generation of relatively complex configurations is extremely hard and subject to errors. The automatic generation approaches in use have geometric limitations and deal only with plane joints. A new especialized automatic mesh generation approach by computer is presented. It is neither restricted to standard joint types nor to plane configurations. The meshes are generated for real joints. The user especifies the refinement degree which is completely variable.
