Abstract

Un método para identificar una deformación límite de estrechamiento de una lámina metálica de conformidad con la presente invención incluye un paso (S1) para medir la distribución de la deformación en una dirección ortogonal de tracción en un proceso de deformación por tracción de una raíz de muesca (5a) para dos o más tipos de muestras de lámina (1) que tienen una geometría de muesca (5) en una porción de un borde de la lámina (3); un paso (S3) para obtener una relación del incremento de la deformación de la raíz de la muesca (5a) en el proceso de deformación por tracción y un gradiente de deformación en la dirección ortogonal de tracción; un paso (S5) para obtener la deformación límite de estrechamiento en la que se produce el estrechamiento en la raíz de la muesca (5a) con base en la relación del incremento de la deformación en el proceso de deformación por tracción; y un paso (S7) para identificar la deformación límite de estrechamiento en función del gradiente de deformación a partir de la relación entre la deformación límite de estrechamiento obtenida para los dos o más tipos de muestras de lámina (1) y el gradiente de deformación en ese momento.
