Abstract

"MéTODO, APARELHO, COMPUTADOR E MìDIA PARA ANáLISE ESTRUTURAL DE OBJETO". Onde as tensões em um objeto são modeladas pela análise finita de elementos, através de elementos ocos opostos (20, 22) definidos em um malha de superfície. A malha de superfície é gerada sobre uma representação da superfície exterior do objeto; uma pluralidade de elementos ocos excêntricos (20, 22) é definida por nós (a, b, c, d, e, f, g, h) na superfície exterior, com espessuras iguais à metade da espessura do objeto nos elementos ocos (20, 22); restrições de múltiplos pontos são estabelecidas entre os elementos ocos opostos correspondentes dos nós (20, 22); condições limitrofes e condições de carga tais como cargas dinâmicas, estáticas ou térmicas são especificadas; e o deslocamento, o esforço e a tensão correspondentes são calculados. O método é aplicável, por exemplo, à análise estrutural e de deformação das peças moldadas a injeção que possuem paredes finas.
