Using Axisymmetric Solutions to Estimate the Forming Severity of Three Dimensional Metal Stampings

This paper presents several guidelines useful when applying axisymmetric solution techniques to the problem of estimating the forming severity of complex three dimensional stampings. Although the axisymmetric solutions are seemingly restricted in their number of applications, these two dimensional techniques can be used to analyze a wide variety of stamping configurations. However, great care must be taken to ensure that the underlying requirements of Axisymmetry are not “seriously” violated. Presented in this paper are several guidelines, including a discussion of the rationale behind them, suggesting how to apply AS solutions to stretch and shrink flanging stamping operations.
