Method and device for implementing of combined folding combining static and dynamic (pulse-magnetic) loadings; The procedure of calculation of the combined technology on the basis of the finite-element method taking into account static and dynamic types of loading without stopping the process; Results of computer simulation of the folding process taking account of properties of the material and its interaction with the tool and allowing to determine completely the sizes and stressed-deformed state of the blank material at any time of deforming; Mechanism of deformation depending on the form and intensity of load, geometrical sizes, properties of the material of the blanks being processed;
