This layer applies and demonstrates novel meta-material and other related absorber concepts or the design of foundations and support systems to protect structures against broad-band excitation in all three spatial directions. The research work is divided in 4 individual research tasks as follows:
ESR06 –Conceptual design of micro-structured materials based on elements subject to frictional forces and capable of self-oscillating under a steady-state input.
ESR07 – Analysis of non-linear physical mechanisms, based on unstable dynamic potentials, which lead to “negative stiffness forces”. Applications to the protection of monuments and high-rise slender structures.
ESR08 – Conceptual Design and development of seismic isolation bearings for structures and large assets based on additively manufactured elastomer/steel pentamode materials confined between steel stiffening plates.
ESR09 – Conceptual design and development of seismic and low-frequency protection devices exploiting the 3D ‘negative stiffness’ concept.
