Consideration of Bauschinger effect based on a reduced texture approach for improved springback prediction with computational efficiency

Abstract

This study introduces a reduced texture approach to efficiently describe the plastic behavior of AA6022-T43. By reducing the number of orientations in Finite Element (FE) analyses, the reduced texture approach improves computational efficiency while accurately predicting plastic responses. The approach calibrates a small number of crystallographic orientations using mechanical test results. By incorporating a kinematic hardening model, it captures Bauschinger effect, transient behavior, and permanent softening. Its predictive accuracy is also validated in springback, a critical challenge in sheet metal forming. The results confirm its potential as a computationally efficient alternative to continuum models for large scale engineering problems.
