Abstract

Single point incremental forming (SPIF) process has great potential for rapid prototyping and small batch production. Numerical simulation of SPIF process is a very time-consuming process. The non uniform thickness distribution is one of the drawbacks of SPIF process. In this study, an attempt has been made to investigate the thickness behavior using numerical and experimental investigations. The three simulations were performed by means of various hardening laws. This study incorporates the implementation of Hollomon power-law, von Mises yield criterion, and Hill-1948 yield criterion. SC8R shell elements were employed in the simulations which show good results for forming of pyramid frustum with 45-degree wall angle of the AA5052 H32 material. The numerical results in finite element simulations were compared to the thickness results of experimental work. The accuracy of the Hollomon power law was found to be higher than other simulations. All the three simulations have shown the satisfactory results within 5% error value.
