Springback Behaviour in Sheet Metal Forming for Automotive Door

This project is basically an investigation of springback behavior during sheet metal forming process on different parameters by using numerical method. Non linear numerical simulation was performed by using finite element commercial ABAQUS/CAE software. Two different parameters were used in the simulation, which is the material type of sheet metal and the sheet thickness. In evaluating the effect of material types on springback behavior, the boron steel (AISI 15B48H) and composite (Carbon fiber reinforced plastics) were used. The computational results show the carbon fiber reinforced plastic has less springback than the steel. The computational results show that thicker sheet exhibits smaller springback compared to thin sheet. The results were verified with available data obtained from literature. Current and future trends on automotive door are briefly discussed in this project and some recommendations are made in order for future development of the simulation.
