Solving the problem of shaping aircraft skin parts by wrapping through the internal geometry of the surface

According to the results of the analysis, it was revealed that the rigid binding of the shell's parts surface of the skins to the bypass forming contours of the coverage does not allow us to detect some properties of circulation associated with their internal geometry, regardless of the three dimensional space of the coverage itself. If the surface of the shell part is sheathed beyond the lines of curvature in specifying orthogonal coordinate lines, then the shape of the stretch punch can be similarly characterized by changing the geometry of the Earth's surface. In this case, the orientability of the surface of the tight punch relative to the main line of curvature along the shaping contour, the direction of which is determined by the direction of the impact during tightening. Such a coincidence is found when monitoring the symmetrical development of focal deformation and the predominant formation of a plastic deformation zone in the foci of partial sheet deformation. As a result of solving the problem of shaping the shell parts of the skins by tightening, which is found to be detected in various sheets of the workpiece and the absence of wrinkles and ruptures.
