In this paper the evolution of the Young’s Modulus (E) during unloading with plastic deformation has been studied for different Dual-Phase AHSS from DP780 to DP1400. During unloading, all the DP steels studied showed the presence of microplasticity so an Apparent Young’s Modulus (EA) has been defined. Although that in all cases EA decreased with a nonlinear behavior as the plastic strain was in...

A scale bridging approach combining the FE method with parallel domain decomposition (FETI) is presented. The FETI approach is used in the project “EXASTEEL Bridging Scales for Multiphase Steels” (within the German priority program “Software for Exascale Computing SPPEXA”) for the simulation of modern dual-phase steels. This approach incorporates phenomena on the microscale into the macroscopic...
