Numerical Simulation of Thick Sheet Slitting Processes:Modelling Using Continuum Damage Mechanics

摘要：

　　This work consists on the modelling and numerical simulation of specific cutting processes of thick sheets using advanced constitutive equations accounting for elastoplasticity with mixed hardening and ductile damage.Strong coupling between all the mechanical fields and the ductile damage is accounted for.First the complex kinematics of the slitting process is described.Then,the fully and strongly coupled constitutive equations are presented.Finally the influence of the main technological parameters of the slitting process is studied focusing in the minimization of the cutting forces.
