Abstract

La posibilidad de fractura de un material se evalúa cuantitativamente por la comparación de la relación entre los datos obtenidos por un análisis numérico usando una técnica de elementos finitos y una línea de esfuerzo límite de fractura, usando una línea de esfuerzo límite de fractura, que se ha provisto mediante la conversión de la proporción de expansión del agujero al esfuerzo, como un criterio de fractura o rompimiento. De acuerdo con la construcción anterior, en la determinación de un límite de fractura de una parte de reborde o brida de elongación en una placa delgada en un curso que incluye uno o más cambios del proceso de deformación, la línea límite de fractura o rompimiento se puede determinar fácil y eficientemente para predecir la fractura con una alta exactitud y así evaluar la posibilidad de fractura en la presión o colisión.
