Vibration Absorption Systems and Energy Absorption Structures
This work focuses on the development of energy absorbing materials that possess excellent mechanical properties such as high strength, low density and ideally high stiffness (directional and/or flexural) while having the ability to reduce vibrations over a range of frequencies and absorb large quantities of energy without plastic deformation. Several structured materials, such as periodic lattice materials and metal foams, have high damping coefficient and low weight; functionally graded materials, and honeycomb structures have the potential to absorb vibrations and are ideal for aerospace applications.
These materials may be used as core materials for sandwich structures commonly found in aerospace applications. Suitable materials will be identified for energy absorption applications, methods to optimise topology and microstructures of the cellular materials and modelling of the macroscopic behaviour of the materials will be performed in this project to add to the existing knowledge and understanding of such materials.
