title = "Investigation on Springback Behavior of Multi-intersecting High Stiffened Structure in Die Forming",
abstract = "Multi-intersecting high stiffened structures have potential application in aerospace components, which are the main load-bearing structure of manned space station. However, its springback behavior is very complicated due to the interaction of multi-intersected ribbons and intersecting patterns during die forming. In this study, for typical spherical shaped multi-intersecting stiffened structures, a new approach is proposed to quantize the influence on flexural neutral layer of multi-intersected ribs. The strain distribution along the thickness at different radial positions of ribs is derived theoretically. Reverse loading method is used to calculate springback radius of each position assisted by Matlab software and the radial profile of the panel after springback is obtained by numerical integration algorithm. To verify the accuracy and effectiveness of the new approach, finite element simulations based on ABAQUS software and experiments were both implemented. Comparison shows that the results are of good agreement, proving the approach is capable of predicting springback of multi-intersecting stiffened structures.",
