We discuss here the main result found in this study: the ratio h/z of the radial exponential scalelength h to the constant scaleheight z is about twice smaller for interacting galaxies. This is found to be due both to a thickening of the plane, and to a radial stripping or shrinking of the stellar disk. If we believe that any galaxy experienced a tidal interaction in the past, we must conclude that continuous gas accretion and subsequent star formation can bring back the ratio h/z to higher values, in a time scale of 1 Gyr.8 pages, 7 figures, latex.
