Abstract
In large-scale numerical simulations of sheet metal-forming processes there is a need for assessing wrinkle formation tendencies at early st ages of the computations. An algorithmic procedure for early predictio n of wrinkles is presented, that makes use of the continuum mechanical behaviour of elastoplastic structures near buckling. The procedure ha s been implemented into an explicit finite element code and the perfor mance is demonstrated on some example problems. (C) 1997 John Wiley & Sons, Ltd.
