An analytical study on elastic flange wrinkling of laminated circular plates in deep drawing process

Based on two -dimensional plane stress wrinkling model of an elastic annular plate and a bifurcation functional from hills general theory of uniqueness for polar coordinate, the critical conditions for the elastic wrinkling of the flange of a two layered circular bland during the deep -drawing process are obtained analyticaly.
