Abstract
Finite element models were developed and used to predict springback and residual stresses in a solid plate due to bending. This paper presents the modeling issues that were involved in the development of the optimum finite element tool and discusses the effects of the different input parameters on springback. A sensitivity analysis concluded that the springback depended on the bent angle as well as other various parameters such as tool and die geometry, part geometry, material characteristics, and the pre-bending residual stresses. A “probabilistic” approach was taken to determine the sensitivity of the model to the above mentioned parameters. The results of preliminary validation of springback are also presented.
