Abstract and keywords

The ductile damage of automotive aluminum sheet alloy AA5754-H111 is investigated by experiments and numerical simulation using the Gurson-Tvergaard-Needleman (GTN) model. The GTN parameters were determined by a uni-axial tensile test and the inverse finite element method. The same parameters were employed to provide the ductile damage behavior of central cracked panel (CCP) specimens. A good prediction can be established among the numerical simulation and experimental data in from of the force opening displacement. As an application, the identified GTN model is used to predict the influence of cold working on deformation and ductile damage. The numerical simulation results obtained are assimilated with experimental data.

Keywords: GTN model, ductile fracture, AA5754-H111, cold working
