Giordano call it (the set) Rigid Clearance Domain. The displacements are the components of the torsor of small displacements of a frame attached to one surface from the other one. 2.1. Substitution surface The model we use is based on the concept of associated surfaces. This one is attached to the measured surface (skin model) with a specific criterion (mean squares, …). In the following, we assume that all surfaces are associated surfaces. We build a frame on each joint (associated) surface of the system as shown in figure 1. Thus, a joint will have two frames, one for each part attached to the joint. Figure 1 Associated Surfaces 2.2. Clearance Torsor a...
