Experimental and Computational analysis of springback in dual phase steels

In this work the comfortability of dual-phase automotive steel DP600 is studied through uniaxial tensile tests and V-die bending in different directions relative to rolling direction. A microstructural analysis was also carried out each characteristic region deformation zone, evidencing changes morphology microstructure grains. Additionally, plastic anisotropy material by implementing constitutive models known as Hill-48 Barlat-89. The results showed an increase elastic recovery at 45 ° 90 from This variation can be attributed martensite that created preferential location zones within during process. two Barlat-89 correctly describe yield surface obtained experimental out. simulation using finite element method model gave satisfactory prediction compared with test.
