Abstract

Esse Projeto de Pesquisa - Jovem Pesquisador - fornecerá foco e inovação para otimização de estruturas na indústria offshore. O projeto permitirá que isso seja alcançado fornecendo tempo e recursos humanos para desenvolver novos conhecimentos em otimização topológica multifísica com carregamentos dependentes do design estrutural. Métodos baseados em fronteiras bem definidas (variáveis de função level set e discretas) serão desenvolvidos para acomodar individualmente os diferentes tipos de carregamentos estáticos e dinâmicos impostos pelas condições offshore, incluindo pressão hidrostática, escoamento de fluidos, acústica subaquática, entre outros. As metodologias desenvolvidas serão então combinadas em casos de múltiplos carregamentos de forma a representar mais realisticamente o cenário offshore. Contando com um time baseado em Santos-SP e colaboradores nacionais e no exterior, a pesquisa desenvolverá métodos e códigos computacionais para projetos estruturais inovadores em engenharia offshore.
