Singularities of Parabolic Inhibited Shells,a partial differential equation involving only one component of the displacement. We obtained general results on the orders of the singularities of the displacements and on their propagation, which depend strongly on the nature of the middle surface of the shell (parabolic, hyperbolic or elliptic).

Singularities of Hyperbolic Inhibited Shells,e are two asymptotic directions. Concerning the singularities emerging when . 0, some aspects are very similar to the case of parabolic shells. For instance, singularities along characteristics are more singular than the loading . (at least for the normal displacement .) and propagate.

Introduction,Thin shells are three-dimensional structures with a dimension (the thickness) small with respect to the two others. Such thin structures are widely used in automobile and aviation industries, or in civil engineering, because they provide an important stiffness, due to their curvature, with a small weight.
