Abstract

The use of sheet metal forming simulations has reduced lead-times and costs for the development of new forming component significantly. The accuracy of the simulations is to a large extent dependent on the quality of the material properties provided as input to the simulations. Improving the quality of the material properties is the key factor in order to further increase the accuracy of the simulations. This study is focused on the forming limit properties of AISI 1008 sheet metal. In this paper among the various well-known analytical and empirical methods, Singh-Rao model, Swift-Hill model and NADDRG model are used for analytical prediction of FLD.  The assumptions made in each method are emphasized and their effects on the predicted forming limits are demonstrated. There are many methods for finding the experimental FLD. In the present study experimental work has been performed using Limiting Dome Height test and Erichsen test for finding the FLD. Experimental Set up for Limiting Dome Height test is prepared and find the forming limit is obtained by circle grid analysis method. Standard Erichsen cup test apparatus is used to perform required test. The results obtained during experimental study is reported along with the result obtained using analytical methods.
