FINITE ELEMENT ANALYSISOF PERFORATED SHEET METAL (PSM) FOR OPTIMUM FORMING PROCESS
Keywords:
Deep Drawing, Simulation, RSMAbstract
Perforated sheet metal is having less weight and same strength compare to plain sheet. It is widely
used in screens, filters, shields and guards. It is also used in architectural design. Wrinkling and stress intensity at
the curved portion are the major problems which decreases the life of the product. This work is about to identify
optimum forming parameters like punch velocity and co-efficient of friction to reduce wrinkling and stress
intensity. Experimental results by UTM Machine will be validated with simulated results by DEFORM-3D
software. RSM is used for relationship between input process parameters and responses.
