Investigation and Parametric Analysis of Steel Perforated Sheet Metal (PSM) for Optimum Forming Process

This research paper deals with the finite element analysis of forming process of Steel perforated sheet metal (PSM). Simulations are conducted to scrutinize the impact of material thickness, type of blank, blank shape, shape & pattern of perforation, pitch of perforation etc on stress and load-displacement curve for set of results. Modeling of part files are done on software CATIA V5 which is later imported to FEA software package. Numerical method is used to determine optimum results with reference to process parameters as blank thickness punch velocity and stress distribution during the process on the sheet metal. Weighted Principal Component Analysis a multi response objective optimization method is used to derive best parameters for minimizing the induced stress value.
