Propagation d’ondes élastiques guidées par la surface d’une cavité cylindrique de section arbitraire. (Propagation of elastic surface waves along a cylindrical cavity of arbitrary cross section). (French) Zbl 0617.73029

(Authors’ summary.) We prove the existence of a hierarchy of elastic modes guided by the surface of a cylindrical cavity. Two of these modes propagate whatever the wave number are. All of the others exists only beyond a certain threshold.
