TI - Numerical analysis of sheet metal forming: the corrugation effect PY - 2006/// N1 - Dane z autopsji N2 - A new approach to solving the problem of the sheet-flange corrugation in the process of forming cylindrical sheet-metal elements is presented. A brief characteristic of the dynamic central-difference method is given. Technological parameters of a forming disk, a die block and a plunger die have been selected from references. Sample results of computer simulations with stress distributions in a disk are presented and serve as the basis for discussing the process of sheet metal forming ER -
