No geral, o método BESO aplicado à estruturas circulares, tanto na análise estática quanto na análise dinâmica, mostrou-se eficaz tanto do ponto de vista da estabilidade numé- rica quanto do ponto de vista do custo computacional. Como continuação do trabalho aqui desenvolvido, são sugeridas:
• Utilização da redução de modelo cíclica simétrica no problema dinâmico e sua aplicação na Otimização Topológica;
• Maximização de outras frequências naturais das estruturas circulares;
• Implementação da otimização no projeto de volantes de inércia cíclicos simétricos, consi- derando a rotação em regime permanente da estrutura e a dependência de carregamento devido às forças centrífugas;
• Implementação de iteração fluido-estrutura para o projeto de impelidores de bombas centrífugas;
• Implementação do método desenvolvido para problemas tridimensionais cíclicos simétri- cos.
