Abstract:
1. A method of assembling an axially extending member made of a first material in a part made of a second material having no plastic domain, comprising: a) forming the part with an aperture and pierced holes distributed around the aperture intended to form elastic deformation means; b) inserting a radially flared portion of said member into the aperture without any stress; c) elastically and plastically deforming the flared portion of said member in the aperture by moving two tools towards each other axially, respectively on top and bottom parts of said flared portion, so as to exert a radial stress against the wall of the part surrounding the aperture, by stressing said elastic deformation means of the part, in order to secure the assembly in a manner that is not destructive for said part.
