Nonlinear multiscale structure optimization: vibration, cloaking and snap-through

If you have a question about this talk, please contact Shehara Perera .

We will introduce the multiscale optimization of graded lattice micro-structures which enable useful and potentially unintuitive behaviour at the macroscale. We will first consider a vibration control case in which the macro-scale dynamic modes and resonant frequencies of a structure can be precisely tailored without changing the global geometry and mass. This has particular relevance for the design of structures designed for launch applications. It will then be demonstrated how the inclusion of geometric and material nonlinearity in the optimization enables unusual emergent properties, including mechanical cloaking and the synthesis of microstructures exhibiting snap-through and bistable responses.
