Response Surface Metamodel to Predict Springback in Sheet Metal Air Bending Process

Jaber E. Abu Qudeiri, Fayez Y. Abu Khadra, Usama Umer, and Hussein M. A. Hussein
Abstract—The springback amount in the air bending process is influenced by a number of material’s geometrical parameters. To predict the springback a multidimensional function should be approximated. In this paper a response surface metamodel is utilized for this purpose. A verified nonlinear Finite Element (FE) algorithm is developed to generate the training data. Then, the generated training data will be used to train RSM. The FE algorithm is developed based on the updated Lagrangian formulation. To select the training data for the RSM, computer generated D-optimal designs are utilized.

Index Terms—Metamodels, springback, response surface, D-optimal designs.
