Numerical Simulation of Fine Blanking Process Using Fully Coupled Advanced Constitutive Equations with Ductile Damage
This paper presents the modelling and adaptive numerical simulation of the fine blanking process.Thermodynamically-consistent constitutive equations,strongly coupled with ductile damage,together with specific boundary conditions (particular command of forces on blank holder and counterpunch) are presented.This model is implemented into ABAQUS/EXPLICIT using the Vumat user subroutine and connected with an adaptive 2D remeshing procedure.The different material parameters are identified for the steel S600MC using experimental tensile tests conducted until the final fracture.A parametric study aiming to examine the sensitivity of the process parameters (die radius,clearance die/punch) to the punch force and fracture surfaces topology (convex zone,sheared zone,fracture zone and the burr).
