The research will address three types of wrinkling problems in                  sheet metal forming:  (1) wrinkling of metal sheets in finite                   stretching and unequal edge constraints; (2) wrinkling of                       unevenly stretched metal sheets; and (3) wrinkling of partially                 stretched metal sheets.  Each of these three problems can be                    divided into two parts: prewrinkling finite deformation and                     bifurcation analysis.  By taking a unified approach to the                      problem of wrinkling, a scientific approach to preventing                       wrinkling during forming will be developed.
