Abstract
Patente de Invenção: <B>"MéTODO PARA MODELAR A FORMAçãO DE CHAPAS ANISOTRóPICAS"<D>. Método para fabricar um artigo de um blanque (12) de um material (por exemplo, chapa de liga de alumínio) que tem propriedades de deformação anisotrópicas, com um ferramental (14) o qual foi projetado pela previsão do fluxo e deformação do blanque (12) utilizando uma análise a qual separa as propriedades de deformação anisotrópicas do blanque (12). O método calcula a resposta de uma pequena quantidade do blanque (12) utilizando a teoria da plasticidade dos cristais. O blanque (12) pode ser representado por uma malha que tem uma pluralidade de elementos. Um percruso de esforços é previsto para cada elemento utilizando a análise de elementos finitos (FEA), e uma curva de tensão - esforço é definida para cada elemento executando um cálculo de simulador de pontos do material (MPS) para cada elemento utilizando o seu respectivo percursos de esforços. Uma segunda FEA é então executada nos elementos utilizando as respectivas curvas de tensão - esforço para cada elemento. A curva de tensão - esforço para cada elemento pode ser definida designando para cada elemento uma curva que fica entre uma curva de limite superior e uma curva de limite inferior, utilizando vários métodos. O modelo computacional requer muito menos tempo de CPU comparado com os métodos da técnica anterior.
