Résumé

An elastic shell filled with and submerged into different fluids is subjected to an external acoustic pulse. It is found that the diversity of the internal reflection and focusing phenomena is such that it leads, for certain combination of the parameters of the fluids, to a very considerable increase of the pressure in the fluid which in some cases can be as high as 110% of the peak incident pressure. A thin elastic circular cylindrical shell filled with and submerged into different fluids is considered. The fluids are assumed to be irrotational, inviscid, and linearly compressible, thus the wave equations are used to model the fluid dynamics. The results show that the tensile stress is affected by the changes of the acoustic properties of the fluids, so much so that it prompts a separate discussion of the matter.
