The use of finite element modeling for metal forming processes allows the reduction of trial and error of the manufacturing process and thus contributes to achieving high precision of the part geometries. However, the localized deformation and the long process time observed in Incremental Sheet Forming (ISF) provide a challenge in the selection of finite element modeling tools and process parameters (e.g., FEA software, constitutive material model, mesh type, element size) and in obtaining accurate results with acceptable computational costs. In this work, a comparative study is conducted for a truncated 45° cone of AA7075-O manufactured by the two point incremental forming (TPIF) process. The cone is modeled using two different commercially-available software, Abaqus and LS-Dyna, which hold different combinations of constitutive material models and numerical parameters. The simulation results were compared with the experimental measurements of the geometric profile, thickness distribution, and forming forces to give a best practice guideline in modeling ISF that achieves accuracies within desired computational costs.
