<p>The invention relates to a sandwich structure capable of working three-dimensionally and to achieve hysteresis-type characteristics with geometrical non-linearities, with ascending elastic elongation and to a device made by using said sandwich structure, capable of absorbing and damping static and/or dynamic loads. According to the invention, the structure comprises a packet (A) made of generally truncated cone-shaped elastic laminae (1) which can also be cylindrical or flat, the said pachet being prestretched by means of a lower and an upper rigid deforming members (2 and 3) having the same geometrical shape as the laminae (1), the contact surfaces (a and b) thereof being generally bent according to a spherical, ellipsoidal or conoidal geometry and joined to each other along some sufaces (c and d) which are made in such a manner that a hollow zone of the first contact surface (a) corresponds to a convex zone of the other surface (b) and vice-versa, while the lower member (2) has an external cut-out (e) on which there rests a shoulder (j) of an attachment member (4) whereonto an upper member (3) is fixed, preferably in a non-dismountable manner.</p> |
