Definition and Use of Swaging

Swages are by appearance and use very similar to small stiffeners welded to the plate. However, they are generated as component types of their own via the SWAGE statement. Details about how to generate swages can be found in Hull / Planar Modelling / Design Language of Hull Modelling / Swage Statement.

Swages are formed by pressing the plate by a tool against a counter-part (a dye). Thus the extension of the plate will become smaller in the fabrication process. Correspondingly, the size of the plate before applying the swaging must be extended compared to the nominal size. This is done automatically when extracting parts from the hull model in the ppanparts module. The symmetry line of each swage (and optionally some additional information) is in this process added to the plate as a marking line in a similar way as for ordinary stiffeners.
