Characterization of Structural Behaviour for High Frequency Phenomena

Obiettivo

The use of composite materials as principal structural elements in an aircraft requires the complete understanding of their mechanical properties. In particular, when structure is subjected to high frequency loading conditions (i.e. low and high energy impacts) phenomena as wave propagation, strain rate dependences, delaminations and rupture need to be fully understood. This is crucial to obtain certification of aeronautical structures like those proposed within the “Clean Sky - Green Regional Aircraft” initiative.

Current numerical models are based on tests and technologies developed during the nineties in European R&T Programs. Since then, significant progress has been achieved in the development of physically-based models and multiscale modelling strategies, which provide more accurate results and can be applied to different materials. In the CRASHING project, the state-of-the-art in multiscale simulation of composites will be transferred to the current numerical tools used by the industry in the simulation of the mechanical behaviour of composite structures for aerospace applications. The project will be focused in composite materials currently used in aircraft innovative designs. In addition, new materials with potential application in the future will be assessed with respect to the database generated along the project.

The objective of CRASHING project is to develop multi-scale model approach that takes into account the physical mechanisms of damage at the different length scales so the influence of the microstructure and loading conditions can be taken into account rigorously. The multiscale approach describes systematically the material behaviour at different length scales from ply, laminate to component levels. Final models of the multi-scale approach will be suitable for simulations of aircraft crash-landing, ditching, bird strike, ice impacts and, in general, situations where the aircraft is subject to high frequency dynamic loads phenomena.
