Sheet metal forming is a basic manufacturing process for the mass               production of numerous commercial products.  In sheet metal forming,            wrinkling is a major type of failure which has been recognized for a            long time but remains to be solved.  Wrinkling may occur in any stage           of a forming process including the springback stage.  The acceptance            of a sheet metal product depends on the final physical state which              may be determined by a post-birfurcation analysis and a springback              analysis.  A post-bifurcation analysis describes the growth or decay            of wrinkles after their initiation.  This research will attempt to              develop a general solution of the wrinkling problem including the               post-bifurcation behavior of wrinkles.
