Although advanced high-strength steel (AHSS) demonstrates excellent uniaxial tensile formability, its application in automotive parts is limited due to inferior flange formability. Despite extensive efforts to enhance the flange formability of AHSS,

The effect of the hole-edge condition on the hole-expansion ratio (HER) of ferrite-bainite (FB) dual-phase steel is analyzed by developing a dual-scale finite element (FE) approach. The proposed dual-scale approach consists of macroscale simulation o

A dual-scale finite element model is proposed to investigate the failure of ferrite-bainite (FB) dual-phase steel in the hole expansion test. The first level simulation solves the elastic-plastic deformation behavior with phenomenological isotropic e
