Formatted abstract
Incremental Sheet Forming is a sheet metal manufacturing process that involves rather complex contact mechanics models due to the small thicknesses of the sheets used. Currently FEM solvers are used to predict the forming forces required to deform the sheet into the desired shape. However these methods can take long periods of time to accurately solve for these forming forces. This thesis entails using basic contact mechanics models such as the bending of thin plates and plate theory to develop a simpler method of force prediction. This will compute the forming forces in much shorter periods of time while maintaining a reasonable level of accuracy. A method based on plate theory was developed successfully to produce the forming forces in under 0.2 seconds for a groove test on a 300x300x1 mm Al7075 sheet with an average error of 16.5% when compared to measurements taken for the same path experimentally.
