| Abstract: | The stress and strain distributions of outward fringe's convex curvature flanging operations in sheet-metal forming has been analyzed,An approximate mathematical models to predict the blank shape has been estab-lished,also an improved calculation model for the original-sheet dimension of the flanged part is given out.Thus a more precision's tolerance could be achieved in the flanging operation. |
