Abstract
This master thesis shows a study of the waves propagation phenomena inside a layered structure such as the MarkIII cargo containment system (CCS), widely used for the transport of the liquefied natural gas overseas. As a consequence of the wave impacts that take place inside the LNG tanks, strain waves start propagating, reflecting and transmitting at the interfaces which compose the layered structure. The aim of the thesis is to better understand how the propagation of strain waves inside a material resolves the discontinuity between liquid and structure at the moment of the impact, and how the theory of strain waves propagation can be applied to a theoretical model in order to define the deformation of the structure.
