Abstract
Se proporciona una tecnología para evaluar más fácilmente el agrietamiento de los rebordes por estiramiento en una cara de un extremo cizallado de una lámina metálica de ensayo. El método incluye información del gradiente de deformación de referencia (10c) adquirida mediante la realización de un análisis de formación de una prueba de expansión de orificios en una segunda lámina metálica seleccionada aleatoriamente bajo condiciones de formación predeterminadas y la conversión de un índice de expansión de orificios en una deformación en un borde de un orificio compuesta por una deformación real, en donde la información (10c) es una relación entre la deformación en el borde del orificio y un gradiente de deformación a lo largo de una dirección radial, y en donde se incluyen dos o más piezas de la información (10c) al modificar las condiciones de formación. La formación de expansión de orificios se realiza en la lámina metálica de ensayo bajo las mismas condiciones de formación que las condiciones respectivas de formación correspondientes a al menos dos piezas de la información del gradiente de deformación de referencia (10c) para obtener al menos dos índices de expansión límite de orificios en un límite de expansión de orificios de la lámina metálica de ensayo. Una región conformable (ARA) de la lámina metálica de ensayo se obtiene a partir de las al menos dos piezas de la información del gradiente de deformación de referencia (10c) y de los al menos dos índices de expansión límite de orificios obtenidos en el límite de expansión de orificios. El agrietamiento de los rebordes por estiramiento en la cara del extremo cizallado de la lámina metálica de evaluación se evalúa mediante la región conformable (ARA) obtenida.
