FIELD: plastic metal working, namely manufacture of members of outer facing of ship bodies and other complex-shape constructions. SUBSTANCE: method comprises steps of applying successive local bending efforts by one or several transitions along path of isoparameteric lines of equal bending of loaded blank or of equal bending efforts; orienting axis of applied bending efforts along line normal relative to isoparameteric line in plane and relative to plane of bent blank. EFFECT: enhanced efficiency of method. 5 cl, 3 dwg
