Numerical Analysis of Corrugation Development during Oblique Compression of a Plate When Manufacturing Angle Metal Parts

The paper considers the problem of corrugation developing on walls of parts during sheet metal forming. We performed a numerical experiment using Deform-3D software to simulate manufacturing operations pertaining to forming a workpiece in the cramped conditions of the die. We established probabilities and conditions for corrugations developing on the shelves of angle metal parts representing a wide range of aircraft components, such as stringers, stiffeners and structural elements of lattice rudders and wings.
