Abstract. The purpose of this paper is to conduct finite element simulations of the incremental forming process of polycarbonate material. The process was simulated using the commercial software LS-Dyna. An explicit loading-implicit unloading approach for springback was set up, reproducing the experimental conditions. The shell element type and the number of integration points along the thickness were defined through a preliminary numerical approach. A spiral 3D surface was generated and measurements of cone geometry were conducted. The model was validated by comparing experimental and numerical thickness in a cross section, and finally used to investigate the effect of step size on the process mechanics. It was found that a decrease in step size would yield to a more uniform thinning along the profile cross section and produces larger thickness reduction.
