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 constitut...

The residual stresses created by deep drawing of AISI-1010 cups were investigated by means of neutron diffraction. The wall thickness of the cups was below 3.0 mm, for which 8–10 through-thickness measurements were conducted. It was found that the axial, and tangential stress profiles are similar to what is expected from a bending–unbending operation, but it also exhibits a strong dependence on...

Figure 1 shows a simplified CAD representation of the tools and initial blank in the stamping process. During stamping, the metal sheet is submitted to large displacements and large elasto-plastic strains; rupture and wrinkles must be avoided, (Figures 2 and 3). The resulting part must also satisfy quality requirements regarding its geometry: after tools removing, the springback effect (Figure ...

The residual stresses that occur in the machined parts after the tools removing are the main cause that determines the springback of the draw parts made from metal sheets. Hence, to investigate this instability phenomenon it must be known the state of residual stresses developed in the part by its machining. But, the experimental investigation of the residual stress distribution in the case of ...
