Abstract: The behaviour of lightweight structures subjected to dynamic loading has become a critical issue in the designing process. Due the weight reduction requirement, structure can not be improved by increasing its thickness and therefore it is needed a detailed knowledge of the behaviour of this structures when subjected to this conditions. During the last decades, different industries have acknowledge this fact, for example, aerospace industry has analyzed widely the behaviour of metallic and composite structure when subjected to low and high velocity impacts.  Nowadays, other industries such the transport, energy or civil infrastructure has increasing the research on this particular scope.

The talk will begin with an introduction to the research of the Lightweight Structures Dynamics research group. This group is composed by researchers from different specialities all focused on the behavior of structures in dynamic regime. Different experimental methodologies for conducting complex impact tests at high and medium speed have been developed. Likewise, the group has extensive experience in performing models for materials under high strain rates, and developing simple analytical models for modeling impact phenomena. Research projects with both public and private funding are carried out, having worked with major companies mainly in the aeronautics sector, such as Airbus, Aernnova, ITP, etc. are EADS ... In addition to this activity, the group disseminates its findings through research articles in various indexed journals, as well as scientific conferences, mainly international.

Then, it will be shown a particular example of the studies done by the research group. In this case, the behaviour of fluid filled structure when subjected to high velocity impact. When a high-energy object penetrates a fluid-filled container it is generated the Hydrodynamic Ram (HRAM). HRAM is  a particular concern in the design of wing fuel tanks for aircraft because it has been identified as one of the important factors in aircraft vulnerability. In the present work it is presented the experimental campaign  that analyze the aforementioned problem and it is proposed a new method to minimize the damage of the structure.
