Abstract

Un método para el análisis de conformación por presión incluye (1) realizar una transformación de coordenadas para calcular una distribución de tensión (a) antes de una liberación del troquel por presión en un sistema de coordenadas local; (2) realizar un análisis de recuperación elástica que incluye (i) calcular una distribución de tensión residual después de la liberación y realizar la transformación de coordenadas para calcular una distribución de tensión residual (b) en el sistema de coordenadas local; y (ii) calcular datos de forma Cd) después de la liberación; (3) calcular una diferencia (a - b) como una tensión eficaz de SB, realizar una transformación de coordenadas para calcular una distribución de tensión eficaz de SB en un sistema de coordenadas global, cambiando o quitando la tensión eficaz de SB en una región objetivo de análisis y realizar el análisis de recuperación elástica para calcular datos de forma (c) después de la liberación; y (4) calcular una diferencia (c - d) para determinar un grado de influencia de la región objetivo de análisis.
