A Review of Sheet Metal Forming Evaluation of Advanced High-Strength Steels (AHSS)
MetalsThis paper presents a review on the formability evaluation of AHSS, enhancing necking-based failure criteria limitations. Complementary fracture/damage constitutive modeling approaches specifically tailored to formability evaluation, validated through numerical and experimental methods, are also subjects of research.

Analysis of the Bending Process of HSLA S700MC and AHSS S900MC steels
Abstract HSLA S700MC and AHSS S900MC steels have been increasingly used to substitute conventional steels, and further understanding of mechanical behaviors is needed. This study aims to evaluate mathematical equations for calculating the True Strain in the outer fibers of the bending zone, Springback and Bending Force that occur in the
