Mechanical Response Of Confined Pentamode Lattices For Potential Use As Novel Seismic Isolation And Impact Protection Devices

Dr. Gianmario Benzoni with University of Salerno

The ability of pentamode lattices to have both very soft and very stiff deformation modes suggests they are potentially suitable for use as seismic isolators. Unlike most other seismic isolators, where the response depends entirely on the properties of the materials used, the response of pentamode lattices depends mostly on their geometry. This is advantageous, as their response can be easily tuned by altering the geometry to control the vertical and horizontal stiffness for each application.
