Assembly of a part that has no plastic domain

A method of assembling a 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 an intermediate part, made of a third material and including a hole, into the aperture without any stress;
• c) introducing the member into the hole without any stress;
• d) elastically and plastically deforming the intermediate part by moving two tools towards each other axially above and below the intermediate part so as to exert a radial stress against the member and against the wall of the part surrounding the aperture by stressing the elastic deformation means of the part and to secure the assembly in a manner that is not destructive for the part.
