Abstract
Flow forming is a process that uses rollers to form a disk of material over a rotating mandrel. The purpose of this thesis is to develop a model of the flow forming process using large strain, explicit finite element analyses. Both two- and three-dimensional models were developed and tested. Both models predicted the wall thickness of the flow formed part to within 7.1%. The average error in the predicted profile of the bottom of the part was within 2.2% after each simulated flow forming pass for the both two- and three-dimensional finite element models. In all cases the equivalent plastic strain predicted by the models was greater than that obtained by direct measurement using a microhardness technique. Overall, the finite element models predicted well the geometry of the flow formed part and displayed promising agreement to the local equivalent plastic strain
